Product Feature of Green silicon carbide grit

Extremely high hardness (Mohs 9.5, Vickers 3100-3400kg/mm2) with high wear-resistance ability.
Excellent chemical resistance and oxidation resistance. When heated at high temperatures, silicon carbide only oxidizes on the surface, forming a silicon dioxide film. The film can protect the silicon carbide material from oxidation.As a result, even in 1600°C ,green SiC can maintain stability to most strong acids and alkalis.
High Toughness.The toughness of silicon carbide abrasive refers to the difficulty of breaking under the action of external force. Taking F46 grit as an example, the toughness of carborundum tested by static pressure method is about 68-78%.Comparing with fused alumina, the mechanical strength of silicon carbide is higher. F120 for example, the compressive strength of silicon carbide is 186KN/cm2, and the compressive strength of corundum abrasive is 100KN/cm2.
Excellent thermal shock resistance with low thermal expansion coefficient. At a temperature of 25-1400 °C, the average thermal expansion coefficient of silicon carbide is 4.4x10-6/°C, while the thermal expansion coefficient of fused alumina is 7-8x10-6/°C.
High temperature resistance; high temperature strength. The melting point of green silicon carbide is 2600 °C, and the maximum operating temperature can reach 1900 °C. Applying silicon carbide to the inner wall of the engine can increase the life of the engine.
High purity. The green silicon carbide grain from us is milling from A grade green SiC block. Then sieve to high consistency particles.

Applications of Green silicon carbide grit

Polishing hard optical glass such as camera lens.
