About Us: http://indus-abrasives.com/6-1-6-green-silicon-carbide-grits.html

Green silicon carbide grit is produced within internal resistance furnaces by mixing high purity silica sand and petroleum coke with high temperatures. The micro hardness of the material is 3200-3400 kg/mm². The weak shape of the individual grains make it used extensively in vitrified, organic bonded abrasives for grinding of cemented carbide tools and also for the manufacture of resistance heating elements in a high temperature furnace as well as the ceramic lapping applications. This material is available in grit sizes, micron sizes, split sizes.
