Micro-nano silicon carbide powder has high purity, small particle size distribution and high specific surface area;
nano-silicon carbide has stable chemical properties, high thermal conductivity (165W/M.K), small thermal expansion coefficient, high hardness, Mohs hardness of 9.5, significant Micro-hardness of 2840~3320kg/mm2 is the first material wear-resistant additive.
its hardness is between corundum and diamond, and its mechanical strength is higher than corundum; nano-silicon carbide has excellent thermal conductivity, and it is also a semiconductor, which can resist high temperature.
Oxidation; nano silicon carbide is wear-resistant, high temperature resistant, corrosion resistant, acid and alkali solvent resistant, widely used in coatings and paints to increase wear resistance.
