High Purity SiC Micro Powder 4N-5N
PRODUCT DESCRIPTION
High purity SiC micro powder, with a purity range of 99.99% to 99.999% (4N to 5N grade) and a particle size range of nanometers to micrometers (usually 0.1 to 10 μ m), has excellent chemical stability, high hardness, high thermal conductivity, and other outstanding characteristics. High purity SiC micro powder core value lies in its extremely high chemical purity, which strictly controls the content of common metal impurities (such as Fe, Al, Ca, K, Na, etc.) at extremely low ppm through precision processes.
High purity SiC micro powder materials are mainly in the α - SiC or β - SiC crystal form, with particle sizes ranging from sub micron to several microns (commonly 0.1-10 μ m), possessing uniform particle size distribution and excellent sintering activity.
This ultra-high purity makes it no longer a raw material for manufacturing ordinary refractory materials or abrasives, but a core raw material for preparing third-generation semiconductor silicon carbide crystals. High purity SiC micro powder is widely used in the fields of third-generation semiconductors, high-end precision ceramics, and advanced composite materials. It is directly used for single crystal growth through sublimation or chemical vapor deposition (CVD), and its purity determines the electrical properties, defect density, and yield of the final semiconductor crystal.
In addition, High purity SiC micro powder is also a key basic raw material for the new generation of electronic devices, the manufacturing of high-performance thermal conductive ceramics (such as high-purity SiC crucibles, substrates), and certain special advanced ceramic composite materials.

PRODUCT DETAIL
High purity silicon carbide micro powder is a material with multiple uses, which can be used in 3D printing technology to manufacture high-strength and wear-resistant components. It can also be used in coatings, batteries, lubricants, catalysts, medicine, grinding industries, electronic devices, ceramic products, and refractory materials. The application areas of high-purity silicon carbide powder depend on its purity, particle size, morphology, and other characteristics. Different application areas may require different specifications of high-purity silicon carbide powder. Uniform color indirectly reflects the consistency of its chemical composition and the stability of its process.
