Cu/Mo/Cu Carrier Price in the Second half of September 2023

8.6x11x0.5mm Cu/Mo/Cu carrier price is 4.00 USD/PC in in the second half of September 2023. These carriers are mainly used in radio frequency, microwave and semiconductor high-power devices, carriers, lead frames, low-expansion layers and heat conduction channels of multilayer printed circuit boards (PCBs).

Cu/Mo/Cu carrier (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 carrier 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.

Why Molybdenum-rhenium Alloys Can Be Used in Space Nuclear Reactors?

Molybdenum-rhenium (Mo-Re) alloys are considered suitable materials for use in space nuclear reactors for several reasons:

High Melting Point: Mo-Re alloys have exceptionally high melting points, with molybdenum having a melting point of approximately 2,623 degrees Celsius (4,753 degrees Fahrenheit) and rhenium around 3,180 degrees Celsius (5,756 degrees Fahrenheit). This property allows them to withstand the extreme temperatures generated in nuclear reactors, ensuring structural integrity under high-temperature conditions.

Thermal Stability: These alloys exhibit remarkable thermal stability, making them resistant to thermal creep and deformation at elevated temperatures. This is crucial in maintaining the structural integrity and performance of reactor components.

High Strength: Mo-Re alloys possess high tensile strength, which is essential for withstanding the mechanical stresses experienced in a space nuclear reactor, especially during launch and operation in space.

Resistance to Radiation: Space environments expose materials to ionizing radiation from cosmic rays and solar radiation. Mo-Re alloys are known for their resistance to radiation damage, making them suitable for long-duration missions in space where radiation exposure is a concern.

Corrosion Resistance: These alloys are generally resistant to corrosion and oxidation, which is advantageous for maintaining the integrity of reactor components over extended mission durations.

Compatibility with Nuclear Fuels: Mo-Re alloys are compatible with various nuclear fuel forms, including uranium and plutonium compounds. They can serve as structural materials, fuel cladding, or reflectors within the reactor core.

Weight Efficiency: Mo-Re alloys are relatively lightweight compared to some alternative high-temperature materials, which is advantageous for reducing the overall weight of space missions.

High Modulus of Elasticity: Their high modulus of elasticity makes Mo-Re alloys suitable for applications where stiffness and dimensional stability are important.

Longevity: The durability and resistance of Mo-Re alloys to the harsh conditions of space, such as extreme temperatures and radiation, contribute to the longevity and reliability of space nuclear reactors.

Molybdenum Crucible Price in September 2023

The latest price of Φ32xΦ28x150mm molybdenum crucible is USD145.00/PC, EXW XIAMEN, CHINA in September 2023. 

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.
