Molybdenum Foil for Vacuum Technology and High-temperature Applications

Molybdenum foil is a thin sheet of molybdenum metal, typically used for high-temperature applications, radiation shielding, and electrical conductivity. The regular thickness of this metal foil can vary, depending on the specific application. It is typically available in thicknesses ranging from 0.001 inches (0.025 mm) to 0.005 inches (0.127 mm). 

The exact thickness depends on the requirements of the application and the manufacturer's specifications. For example, thinner foils may be used for applications where high electrical conductivity is required, while thicker foils may be used for radiation shielding or as a structural component in high-temperature furnace parts.

Molybdenum foil has several applications due to its unique properties:

High-temperature applications: the metal has a high melting point, making it suitable for use in high-temperature furnace parts and in the production of refractory materials.

Radiation shielding: the foil is used in nuclear power plants as a shielding material against radiation, due to its ability to absorb gamma rays and other high-energy particles.

Electrical conductivity: it has a high electrical conductivity, making it suitable for use as a conductor in electronic components and other electrical applications.

Vacuum technology: it is used as a base material in vacuum technology due to its low outgassing rate and high thermal conductivity.

Aerospace: it is used in the aerospace industry as a material for high-temperature furnace components, electrical conductors, and radiation shielding.

Overall, moly foil is widely used in various industrial applications due to its high melting point, high thermal and electrical conductivity, and low thermal expansion.

Glass Melting Molybdenum Electrode Price in Early January 2023

Ø65x720mm glass melting molybdenum electrode price is 2,400.00 USD/PC in the first half of January 2023. This kind of electrode has been widely used in glass melting for many years. 

The electrode made of molybdenum has good advantages of high melting point, high strength and hardness at high temperature, as well as good electrical and thermal conductivity and good corrosion resistance. The use of moly electrodes to replace the original heavy oil and gas energy can effectively reduce environmental pollution and improve the quality of glass. Molybdenum electrode rod is a kind of molybdenum electrode product, its surface is bright gray metallic luster with density more than 10.15g/cm3. They are mainly used for electric glass furnaces, electric light sources and electric vacuum parts.

Cu/Mo/Cu Heat Sink Price in Early January 2023

0.4x3.715x1.5mm Cu/Mo/Cu heat sink price is 1.10USD/PC in the first half of January 2023. 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.

Summary of Uses of Molybdenum Disulfide (MoS2)

Molybdenum disulfide (MoS2) is a two-dimensional layered material composed of two chemical elements, molybdenum and sulfur, with excellent optical, electrical, magnetic, mechanical and thermal properties. It is widely used in energy storage, catalysis, semiconductor, lubrication and other fields. Its main uses are as follows:

1. As an additive for solid lubricants: MoS2 powder is known as “king of solid lubrication", the friction coefficient is between 0.05 and 0.09, and has the advantages of good dispersion, non-sticking and anti-oxidation, etc. It can be added to various greases to form a non-stick colloidal state, which can increase the lubricity and extreme pressure properties of the grease, making it more suitable for high temperature, high pressure, high speed, and high load applications.

2. As a modifier for lithium-ion battery electrode materials: MoS2 is a low-dimensional transition metal layered material with a large distance between layers, which endows it with high lithium ion accommodation capacity and wide ion transport channels. Combined with graphene, it can effectively make up for the lack of low storage capacity of existing pure graphite anode materials.

3. As a catalyst: Because of its high catalytic activity, good chemical stability, preferentially exposed active sites, and long-range/short-range ordered atomic arrangement, MoS2 is expected to replace noble metal platinum to achieve electrochemical hydrogen evolution reaction.

4. Making transistors: Ultra-thin MoS2 transistors with a length of less than 100 nanometers provide greater possibilities for the large-scale popularization of high-performance flexible electronic products such as medical monitors, fitness trackers, smart clothing and foldable smartphones.

5. Used in bionic eyes: Indium-doped molybdenum disulfide has the characteristics of ultra-low power consumption optical synapses, which can effectively reduce the power consumption of bionic eyes and solve the problem of difficult surface processing and integration.

6. For the treatment of joint pain: MoS2 coating is the key material of "targeted nanoprobe" in the nanotechnology of osteoarthritis targeted analgesic diagnosis and treatment.

7. Used in-situ gelation system: A new in-situ gelation system designed by Texas A&M University that does not require photoinitiators uses the photothermal properties of MoS2 and the inherent phase change ability of thermally responsive polymers. Near-infrared radiation activates dynamic polymer-nanomaterial interactions.
