Overview of China high hardness High purity molybdenum carbide Chemical powder
Metal powder is a common form of metal that has been processed into fine particles, ranging from a few micrometers to over 100 microns in diameter. It plays a crucial role in various industrial applications due to its unique properties and versatility.
Features of China high hardness High purity molybdenum carbide Chemical powder
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of China high hardness High purity molybdenum carbide Chemical powder
China is a global leader in the production of high-quality molybdenum carbide chemical powders, known for their exceptional hardness and purity. Molybdenum carbide (MoC), a compound of molybdenum and carbon, finds extensive applications across various industries due to its unique properties.
Molybdenum carbide powder is characterized by its high hardness, typically measured on the Mohs scale, which ranges from 9 to 10.5, making it one of the hardest materials available. This hardness allows it to endure extreme wear and tear in demanding environments, such as in cutting tools, wear-resistant coatings, and abrasive applications. The hardness also ensures long tool life and improved efficiency in machining processes.
Purity is another critical aspect of this material. A high purity molybdenum carbide powder usually contains less than 0.1% impurities, ensuring consistent performance and minimizing the risk of contamination. This purity contributes to better mechanical properties, enhanced thermal stability, and superior chemical inertness, making it suitable for use in high-temperature and corrosive conditions.
The manufacturing process for high purity molybdenum carbide powder in China involves advanced techniques, often starting with the selection of high-grade molybdenum and carbon sources. The mixture is then subjected to controlled sintering or chemical vapor deposition (CVD) processes, which help in achieving the desired particle size, morphology, and density. These processes ensure a uniform distribution of carbide particles, resulting in a homogenous product with minimal porosity.
In addition to hardness and purity, molybdenum carbide powder offers excellent thermal and electrical conductivity, low coefficient of friction, and good chemical inertness. It can be easily machined and shaped into various forms, including powders, granules, or submicron particles, catering to diverse industrial requirements.
Applications of high hardness, high purity molybdenum carbide chemical powder include:
1. Cutting tools: Used in metalworking for precision milling, turning, and drilling operations due to its wear resistance and ability to maintain edge sharpness.
2. Wear-resistant coatings: Applied to surfaces of machinery, bearings, and pumps to extend their operational life and reduce frictional losses.
3. Semiconductor manufacturing: As an etching and polishing agent, ensuring precise surface finishes on microelectronic components.
4. Aerospace: For making high-strength, lightweight components and coatings that withstand harsh environments.
5. Chemical processing: Used in reactors, valves, and pumps for corrosion resistance and high-temperature stability.
6. Energy industry: In the form of tungsten carbide-molybdenum carbide composites, it is employed in oil and gas exploration equipment, as well as in fuel cell components.
In conclusion, China’s high hardness, high purity molybdenum carbide chemical powder is a versatile material with remarkable properties, making it a sought-after choice for various industries worldwide. Its superior performance and durability have positioned it as a key component in modern technology and manufacturing processes.
