Description

Silicon carbide grit Green color

Green silicon carbide 130um F100 mesh is suitable for silicon carbide abrasive wheels. Its hardness of it only ranks after diamond and B4C, and it is harder than black silicon carbide. So it is suitable for grinding a large range of hard materials such as titanium alloy, marble, carbide alloy, optical glasses, ceramics, etc.

Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts of sand and petroleum coke. The SiC purity of green silicon carbide is up to 99%min. It is an artificial brittle SiC with high thermal conductivity and high strength which get no decrease at 1000 centigrade.

Product Feature of Silicon carbide grit Green color

Extremely high hardness (Mohs 9.5, Vickers 3100-3400kg/mm2) with high wear-resistance ability. The hardness of SiC decrease with the increase in temperature. But still, even at the temperature of 1200°C, the hardness of green SiC is about twice that of fused alumina.
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 at 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 the static pressure method is about 68-78%. Compared 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.
