Green carborundum 6000 mesh properties and applications

Green carborundum 6000 mesh is an ultrafine powder with a main crystalline phase of α Silicon carbide, with a hexagonal crystal structure. It corresponds to the national standard model of Green silicon carbide W2.5 powder. It is not only a commonly used grinding material in the field of abrasives, but also a raw material for silicon carbide ceramics, thermal materials, coatings, and polymer materials.

Green carborundum 6000 mesh micro powder has the following properties:

1. The content of silicon carbide is high, and the purity of silicon carbide can reach over 98%. The content of free carbon and magnetic materials is low.
2. The green silicon carbide sorting process is a water-washing suspension overflow process, with a narrow particle size range, with over 90% of particles concentrated between 1-6 microns. The characteristic of uniform distribution is helpful for both polishing and filler material.
3. Green silicon carbide has excellent high-temperature resistance and thermal conductivity. It only dissociates and does not melt at a temperature of 2200 ° C. At the same time, the thermal conductivity of green silicon carbide micro powder is excellent, with a thermal conductivity coefficient of 120W/m · K at room temperature.
4. Green silicon carbide 6000 # has chemical corrosion resistance and can maintain stable physical and chemical properties at high temperatures.
5. Green carborundum 6000mesh  has a Rockwell hardness of 80HRC and a Mohs hardness of 9.5, with high wear resistance.
6. The thermal expansion coefficient of green silicon carbide is very small, with a thermal expansion coefficient of 4.4×10-6/K below 1400 degrees Celsius, indicating good volume stability.

The application of green carborundum 6000 mesh powder includes:

1.  Fine grinding and polishing, mainly used for precision polishing of high-hardness materials. Such as small and precise optical components, silicon wafers, crystals, borosilicate glass, and jadeite.
2.  Wear-resistant and anti-static fillers for modified resin polymer materials.
3.  Anti-corrosion and wear-resistant additives for functional coatings.
4. Raw materials for grinding tools such as oilstones and diamond polishing wheels.
5. Ceramic powder of special silicon carbide ceramics.
