Molybdenum Powder Description
The molybdenum powder comprises tiny particles of molybdenum, a fine grayish-black mass. It is reflected that molybdenum powder enjoys excellent mechanical and thermal properties due to its very high melting point of 2623°C (4753°F) and density of 10.22 g/cm3. Therefore, because of the power and strength of molybdenum powder, it finds a very high demand in various applications where temperature resistance is found to be extreme. It plays a vital role in applications, starting from electronics to aerospace, under conditions where materials have to work efficiently under extreme conditions.

Molybdenum Powder Properties
Molybdenum has good thermal conductivity and a thermal expansion coefficient similar to that of silicon.
Molybdenum can resist corrosion from molten glass.
Molybdenum-rhenium alloys can maintain excellent strength and creep resistance at high temperatures.
Molybdenum powder can be used in steelmaking, and steel alloyed with molybdenum exhibits high strength, high toughness, outstanding heat resistance, and corrosion resistance.
As an alloying element in steel, molybdenum offers the following advantages:
- Increases the strength and toughness of steel;
- Enhances steel's corrosion resistance in acidic and alkaline solutions as well as in liquid metals;
- Improves the wear resistance of steel;
- Enhances steel's hardenability, weldability, and heat resistance.
Molybdenum and Molybdenum Alloy Powder Uses
Molybdenum is mostly used in the steel industry, which makes up about 70% of its use. It is added to different types of steel to make them stronger, tougher, and more resistant to rust. About 15% is consumed in the chemical industry for things like petroleum catalysts, pigments, and lubricant additives. Another 7% goes to the foundry industry to improve the heat resistance and strength of cast iron and special castings. Metal products, like high-temperature alloys and electronic parts, also use about 5%. And the remaining 3% is used in other areas, such as medical devices, glass, and ceramics.
1. Molybdenum Metal Powder (99.0 Mo)
Molybdenum metal powder serves as the primary raw material for producing various molybdenum products. It is processed into desired forms using powder metallurgy techniques or thermal spraying.
- High-Temperature Structural Components: Examples include heating elements, heat shields, and sintering trays in vacuum furnaces or high-temperature sintering furnaces.
- Electronics and Semiconductors: Due to its thermal expansion coefficient being similar to silicon and its good thermal conductivity, it is used to manufacture heat sinks in semiconductor chip packaging and substrates for power semiconductor devices.
- Glass Industry: Used in producing electrodes for glass melting, stirring rods for glass melting furnaces, and refractory components.
- Spraying Material: Can form wear-resistant and corrosion-resistant coatings on workpiece surfaces, commonly used in automotive engine piston rings and synchronizer rings.
2. Molybdenum-Rhenium Alloy Powder
The addition of rhenium significantly improves the plasticity, strength, and recrystallization temperature of molybdenum.
- Ultra-High-Temperature Components in Aerospace: Used to manufacture components subjected to extreme temperatures, such as rocket engine nozzle throats, gas rudders, and leading edges of aircraft.
- High-Performance Electronic Devices: Used for grids and structural components in vacuum electronic devices like traveling wave tubes and magnetrons, which require high reliability and long service life.
- Medical Field: Used to produce rotating targets and critical support components in high-end medical equipment such as CT tubes.
3. Molybdenum-Niobium Alloy Powder
The addition of niobium also enhances the strength and high-temperature performance of molybdenum while maintaining good processability.
- Aerospace: Applications are similar to those of molybdenum-rhenium alloys.
- High-Temperature Furnace Components: Used to manufacture sintering boats and support rods with higher strength and sag resistance compared to pure molybdenum components.
- 3D Printing: Molybdenum-niobium alloy powder is an important material for 3D printing technologies like laser powder bed fusion, enabling the production of complex-shaped, high-performance components that are difficult to fabricate using traditional methods.
4. Titanium-Molybdenum Alloy Powder
Here, "titanium-molybdenum alloy" typically refers to β-type titanium alloys with titanium as the base and molybdenum as the primary alloying element, with Ti-15Mo being the most typical example. It is commonly used in biomedical implants. The Ti-15Mo alloy offers excellent biocompatibility, a low elastic modulus, and outstanding corrosion resistance in bodily fluids. It is often used to manufacture artificial hip joints, femoral stems for knee joints, bone plates, bone screws, dental implants, and prosthetics.
5. Molybdenum Carbide Powder
Molybdenum carbide is a high-melting-point, hard ceramic material with platinum-like catalytic properties.
