Green silicon carbide powder

What are the powdered green silicon carbide’s chemical and physical characteristics?

Physical Properties

1. Density: The abrasive packing density is 1.2–1.6 g/cm3, and the particle density of different green silicon carbide micropowder crystal forms is generally relatively similar at 3.20 g/cubic millimetre.
2. Thermal conductivity: Green silicon carbide powder products have very high thermal conductivity, small thermal expansion parameters, and good thermal shock resistance. It is an excellent refractory substance.
3. Hardness: Green silicon carbide powder has a Mohs hardness of 9.2, which is higher than corundum and ranks second among abrasives only after diamond, cubic boron nitride, and boron carbide.

Chemical Properties

Chemical resistance: A protective coating of silicon dioxide forms on the surface of the green silicon carbide powder crystal when the material is tempered in oxygen to 1300°C. The green silicon carbide powder inside has improved chemical resistance as a result of the larger protective covering, which prevents the particles from further chemical combining. The protective layer of silicon dioxide is removed and the chemical reaction of green silicon carbide powder is enhanced when the temperature rises above 1900 °C (1627°C). Thus, in an environment with chemical compounds, 1900K is the operating temperature of green silicon carbide powder.

Acid and alkali resistance: Green silicon carbide powder has very strong acid resistance and rather weak alkali resistance because of the efficiency of the silicon dioxide protective covering. It also possesses resistance to acids, alkalis, and compounds.
