Descriptions
Green Silicon Carbide is made by a precision water classification process using material that is produced from the reaction between high purity silica sand and petroleum coke appended with industrial salt in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.
Green SiC is an entirely new batch composition made from Silica sand and coke, and is extremely pure. It can be manufactured in many complex bonded shapes, which are utilized for superrefractory purposes. Green SiC is also ideal for a wide variety of abrasive applications.
HIJO Abrasives offers a whole range of macro and micro grits in green silicon carbide, quality and various particle size distributions based on FEPA, and JIS standards.
Bonded & Industrial Abrasives
Ideal for use in vitrified & resinoid grinding wheels, honing stones, blasting, compounds, lapping, polishing and many more applications.
Coated Abrasives
Green Silicon Carbide graded to FEPA standards and is ideal for high quality coated abrasives.
Ceramics
Ideal for many applications including wear resistant seals/rings/nozzles, coatings, metal-matrix composites, kiln furniture, silicon carbide heating elements, body & vehicle armor, and many more.
