There are three types of silicon carbide powder with different production technology. They are Raymond roller milling, jet milling, and water overflow washing. The physical properties of the silicon carbide powders get different as well.
Silicon carbide grit was artificially synthesized at the end of the 19th century. It has achieved large-scale industrial production with several decades of development. Subsequently, silicon carbide grit has become more and more widely used as raw materials for the abrasives industry. Generally, green silicon carbide is used as the raw material for marble and glass abrasive products, and black silicon carbide is used as the raw material for ceramic, stone, cement, and other abrasive products.
Compared with ordinary glass, high borosilicate glass has the advantages of higher mechanical strength, fire resistance, and thermal stability. So it has to get harder abrasive media to polish and finish borosilicate glass. That abrasive media should be green silicon carbide polishing powder.
Black silicon carbide grit is suitable for abrasive tools such as:
Semi-flex grinding wheel
Sanding paper
Sanding sheet
Silicon carbide brush
Abrasive sponge block
Green silicon carbide powder is a very hard grinding media for glass. Even for special borosilicate glass / optical glass/ Quartz glass, green silicon carbide powder can work efficiently.
Both green silicon carbide powder and black silicon carbide powder can work as raw materials for advanced ceramics.
