Molybdenum Foil and Tungsten Foil for Aluminum-ion Battery

Molybdenum foil is a very thin molybdenum sheet. Its thickness usually ranges from 0.002mm to 0.1mm and width should be ≥ 50mm. As the metal foil has the characteristics of high purity, low resistance, good electrochemical performance and chemical stability, it can be used as a current collector in aluminum ion batteries.  

Aluminum-ion battery is a rechargeable battery composed of negatively charged aluminum anode, positively charged graphite cathode, diaphragm and electrolyte, and has similar functions to lithium-ion batteries. Due to the abundant and easy availability of aluminum resources, the use of non-flammable and electrochemically stable electrolytes, and the high theoretical specific capacity of aluminum metal anodes, it has attracted great attention from energy storage researchers.

However, the development of aluminum-ion batteries also faces many problems, such as the current collector, the corrosion of the aluminum negative electrode, and the high cost of the electrolyte. Among them, current collectors with good effect are mostly metal molybdenum foil and tantalum foil with inert characteristics and stable performance within the corresponding voltage range in the electrolyte system, but these metals are rare metals and relatively expensive. 

Molybdenum foil has better electrochemical performance and chemical stability in aluminum ion batteries compared with other cheap metals such as nickel foil and titanium foil. Therefore, it can better ensure the stable operation of the battery. Studies have shown that nickel foil will have chemical corrosion in the aluminum ion battery system, and unfavorable side reactions will occur at low potentials, and the withstand voltage range is narrow.

Currently, moly foil, tantalum foil, nickel foil and titanium foil are all can be applied in batteries as current collectors. In addition, there is a new metal that was found to be usable as well – tungsten. The tungsten foil used in the batteries has advantages of stable electrochemical performance. 

As a professional manufacturer of tungsten and molybdenum for more than two decades, Chinatungsten Online can supply moly and tungsten foils as well as other finished products.

Cu/Mo/Cu heat sink (CMC) is a composite material with a similar sandwich structure, the core material is molybdenum, and both sides are covered with copper. The basic concept of the design is to use the high thermal conductivity of copper and the low thermal expansion characteristics of molybdenum. By adjusting the thickness ratio of copper, molybdenum and copper, it can achieve a thermal expansion coefficient matching ceramic materials and semiconductor materials, and a higher thermal conductivity. The expansion coefficient and thermal conductivity are designable.

The ideal heat sink material should have a linear expansion coefficient CTE, which is basically matched with the chip, and has the highest possible thermal conductivity, especially the Z-direction (thickness) thermal conductivity, so that the heat of the packaged chip and other electronic devices can be quickly discharged. In order to increase its power density, achieve high power, reduce the volume and realize the miniaturization of the device. CMC material is now the one of the materials to meet above requirements.

MoSi2 Heating Elements Are Used in Vacuum Furnaces and Glass Furnaces

Molybdenum disilicide heating element, also known as MoSi2 heating element, MoSi2 heater, silicon molybdenum rod or molybdenum disilicide heater, is an excellent resistance heating element with the advantages of high temperature resistance, low aging, anti-oxidation. 

They are commonly used in various heat treatment furnaces, denture sintering furnaces, experimental electric furnaces, vacuum furnaces, tunnel kilns, roller kilns, casting furnaces, smelting furnaces, glass furnaces and other high-temperature equipment.

According to different shapes, MoSi2 heating elements can be divided into straight rods, U-shaped rods, W-shaped rods, gun-shaped rods, five-section rods, grooved rods, single-threaded rods, and bent right-angle rods. In addition, there are special-shaped products such as MoSi2 through tubes, MoSi2 thermocouple protection tubes, and MoSi2 probes.

No matter what shape they are, a bright and dense quartz glass film will be formed on the surface to protect the inner layer of the silicon molybdenum rod from oxidation when they are used in a high temperature oxidizing atmosphere. However, when the surface temperature of the element is greater than 1700 degrees Celsius, the quartz glass film will melt, gather into droplets, and lose its protective effect. In addition, the components are not suitable for long-term use in the range of 400-700 °C, otherwise they will be pulverized due to strong oxidation at low temperature.

The operating temperature of molybdenum disilicide heating elements is generally 500-1700 ℃. The use temperature of heating elements with different specifications is different; the same heating element can be used at different temperatures in different atmospheres. For example, under air, the operating temperature of the 1700 type element is 1700°C, and the 1800 type element is 1800°C; under nitrogen, the 1700 type element is 1600°C, and the 1800 type element is 1700°C; under nitrogen, the 1700 type and 1800 type elements are used. Both are 1100-1450℃.

In terms of resistance characteristics, the resistivity of molybdenum disilicide heating elements increases with temperature; under normal operating conditions, the resistance generally does not change with the length of use.

Why Molybdenum Hammer Is Important in the Monocrystalline Silicon Growth?

What Is Molybdenum Hammer?

The hammer is usually made of tungsten and molybdenum materials as it is used in high temperature furnaces that require the materials to be heat resisting. 

It is mainly used to connect molybdenum seed holder and tungsten wire rope, and is hung on the suspension clamp or jumper the bottom, increasing the clamp vertical load heavy objects. Although the product can be made from both tungsten and molybdenum metals, as tungsten price is higher than molybdenum, molybdenum is usually the raw material of seed holder with advantages of cheaper price but the same function. Its concentricity requires to be the same as seed holder and tolerance is very strict. The shape corners of threaded need be smooth, high finish.

Monocrystalline silicon is a crystal with a basically complete lattice structure. It is a good semiconductor material with a purity of more than 99.9999%. It can be used for the production and deep processing of diode-level, rectifier device-level, circuit-level and chip products.

Semiconductor grade single crystal furnace is an important crystal growth equipment in the single crystal silicon industry chain. At present, the Czochralski has the advantages of large single crystal quality, large diameter, low cost and high production efficiency, and has always been the main method for the preparation of semiconductor silicon substrates.

The Czochralski is to melt a cooled seed crystal in contact with a silicon melt. When the temperature of the interface is lower than the freezing point, the seed crystal starts to grow. In order to make the seed crystal grow continuously, it is necessary to gradually reduce the temperature of the melt and rotate the seed chuck device to improve the temperature distribution of the melt. When the crystal grows to a certain stage, the seed chuck device must be lifted slowly to expand the heat dissipation surface. Therefore, the reliability and stability of the seed chuck device are very important, and the molybdenum hammer is the key to ensure the reliability and stability.

The latest price of Φ410xΦ380x220mm molybdenum crucible is USD6,300.00/PC, EXW XIAMEN, CHINA.

Corrosion resistance, creep resistance and high temperature performance make molybdenum made crucibles very suitable for high temperature crystal growth processes. When sapphire is easy to extract, higher sapphire yield and quality can be achieved. The molybdenum-based crucible has heat resistance and a smooth surface, making it durable and cost-effective.

The surface roughness of the molybdenum crucible needs to be higher than 1.6 µm. When the surface of the crucible is rough, the sapphire is not easy to take out and it is easy to damage the crystal. In addition, the crucible will be damaged in the process. Chinatungsten Online's ultra-smooth crucible eliminates these problems. Sapphire manufacturers can benefit from this product because it eliminates complex and expensive processes. In addition, the smooth surface is resistant to corrosion caused by aggressively molten sapphire. This function can extend the service life of reusable crucibles.

Moly crucibles for sapphire growth furnaces are available with a variety of dimensions including round, in numerous standard diameters and wall thicknesses. Custom configurations are available. In addition, many other components for these furnaces are also customized.

Will Molybdenum Plates Replace Graphene in the Electronics Industry?

Molybdenum is the most widely used materials in the processing industry. It can be used in the iron and steel industry, most of which are industrial molybdenum oxide briquette directly used for steelmaking or cast iron, a small part is smelted into ferromolybdenum and then used in steelmaking, or synthesized with other metals to make molybdenum plates.

Plates made of molybdenum or molybdenum alloy can improve the corrosion resistance, strength and wear resistance of the original metal. With the characteristics of high melting point, low density and small thermal expansion coefficient, they are also used as an excellent catalyst and lubricant. Molybdenum disulfide plate also has unique anti-sulfur properties, and it is a promising C1 chemical catalyst under certain conditions to catalyze the hydrogenation of carbon monoxide to produce alcohols.

Molybdenum plates have the potential to replace graphene in the electronics industry. Transistors made of molybdenum consume 1/100,000th of the power consumption of silicon transistors in standby conditions and are cheaper than graphene circuits of the same size. However, the biggest change is Its circuit is very flexible and extremely thin, and can be attached to human skin.

The British "Nature Nanotechnology" magazine pointed out that the single-layer molybdenum material shows good semiconductor properties, some of which exceed the widely used silicon and research popular graphene, and are expected to become the next generation of semiconductor materials.

The characteristics of molybdenum plate are that the color, particle size, surface characteristics, dispersity, rheology, thixotropy and crystal form can be manually adjusted, and the product also has high chemical purity, strong chemical inertness, good thermal stability, and are not stable under 400 degrees Celsius. In addition, it also has the advantages of low oil absorption rate, low hardness, small wear value, non-toxic, odorless, tasteless, and good dispersibility.

Cu/Mo/Cu Heat Sink Price on July 26, 2022

0.4x3.715x1.5mm Cu/Mo/Cu heat sink price is 1.10USD/PC on July 26, 2022. They are mainly used in radio frequency, microwave and semiconductor high-power devices, heat sinks, lead frames, low-expansion layers and heat conduction channels of multilayer printed circuit boards (PCBs).

Cu/Mo/Cu heat sink (CMC) is a composite material with a similar sandwich structure, the core material is molybdenum, and both sides are covered with copper. The basic concept of the design is to use the high thermal conductivity of copper and the low thermal expansion characteristics of molybdenum. By adjusting the thickness ratio of copper, molybdenum and copper, it can achieve a thermal expansion coefficient matching ceramic materials and semiconductor materials, and a higher thermal conductivity. The expansion coefficient and thermal conductivity are designable.

The ideal heat sink material should have a linear expansion coefficient CTE, which is basically matched with the chip, and has the highest possible thermal conductivity, especially the Z-direction (thickness) thermal conductivity, so that the heat of the packaged chip and other electronic devices can be quickly discharged. In order to increase its power density, achieve high power, reduce the volume and realize the miniaturization of the device. CMC material is now the one of the materials to meet above requirements.
