Green silicon carbide is produced basically the same as the black silicon carbide, but
different requirements for raw materials. The crystal is high purity and hardness.
1. The main use of size sand
As the abrasive, it is suitable for grinding carbide, hard and brittle metal and non-metallic materials, e.g.: Copper, brass, aluminum and magnesium metals, gems, optical glass, ceramics and other non-metallic materials.
Mainly used for glass polishing, crystal grinding, silicon wire cutting, ceramic polishing, as well as precision grinding wheel manufacturing, plastic products, etc.
2. The use of green silicon carbide powder
Polish machine parts, metal products, cylinder, piston ring, pump, nozzles, bearings, roller ball and precision measuring instruments and polishing glass lenses,
prisms, flat polished crystal and other products.
Silicon carbide powder is also widely used in refractory, wear-resistant floors, ceramic foam, special coatings, corrosion-resistant paint, flow separation and environmental protection industries.
3. Our silicon carbide abrasive grains are manufactured according to
a) FEPA-specifications for bonded F8-F2000
b) FEPA-specifications for coated P12-P2500
The micro grains are available in both blocky and sharp shaped grains as standard
products
4.Typical applications are
a) Grinding wheels
b) Honing stones and sticks
c) Grinding paper and cloth
d) Lapping and polishing powder
e) Wire sawing and polishing of granite and marble
