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.
Green silicon carbide is a perfect material for functions such as non-slip, anti-corrosion, and high-temperature resistance.
Those factors are very important for producing corrosion-proof coating, composite coating such as Teflon, UV cured coatings, Fluorocarbon coating, etc.
Black silicon carbide (Black carborundum) is an artificial abrasive media. The SiC content of A-grade black silicon carbide is up to 98%. After chemically treated, black silicon carbide purity can reach 99%. Although the hardness is not as high as that of green silicon carbide, black silicon carbide is excellent for grinding such as ceramics, stone, and wear-resistant coatings.
