Product Description

 

Black Silicon Carbide Introduction

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).

1. Abrasives:  black silicon carbide  for making grinding wheel, sandpaper, belt, whetstone, grinding block, grinding paste
2. Sandblasting rust removal:  steel, steel pipe, steel structure stainless steel products surface matt treatment, sandblasting rust treatment
3. raw materials of silicon tetrachloride, is the main raw material of silicon resin industry
4. Engineering processing materials: solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials
5. Iron and steel deoxidizer and cast iron structure improver
6. Refractory materials: all kinds of smelting furnace lining, high temperature furnace components, silicon carbide board, silicon carbide crucible, etc
7. Ceramic material: silicon carbide can be used for making advanced silicon carbide ceramic material and sealing ring
8. High temperature indirect heating materials: such as distillation furnace tray, aluminum electrolytic cell, copper melting furnace lining, zinc powder furnace arc plate, thermocouple protection tube
9. Wear-resistant runway: highway, aviation runway
10. Internal placement of discharge pipeline of mine concentrator
11. Other areas: manufacturing semiconductors, lightning rods, circuit components, nuclear fuel
