Descriptions
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.
High purity, good in color, better density, water classified green silicon carbide graded to exacting standards, e.g. FEPA, JIS and custom. HIJO Abrasives green silicon carbide grains are manufactured by various techniques to optimize shape, surface area, density, chemistry and/or particle size distribution for various applications.
