1. Black polishing powder silicon carbide for Rock tumbler grit


 


Because of the rarity of natural moissanite, most silicon carbide is synthetic. It is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F). Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material. The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1,500 °C (2,730 °F).

5. Rock Tumbler Grit


 


Rock tumbler grit


"Rock tumbler grit", also known as "rock polishing grit", is a silicon carbide powder that is much harder than the types of rocks that are commonly polished in a rock tumbler. If it is tumbled in a barrel with rocks and water the abrasion caused by the grit particles rounds the sharp edges off of the rocks. We use about two level tablespoons of grit per pound of rock in a rotary tumbler and 1/2 tablespoon of grit per pound of rock in a vibratory tumbler.

2.Medium Rock Tumbler Grit (150/220 Silicon Carbide)
3.Fine Rock Tumbler Grit (500F Silicon Carbide)Also known as "pre-polish"
