type of product: Silicon Carbide, sizing F14 – F220                       


sizing F14 – F220

1. Silicon Carbide is produced by reduction of silicon oxide by carbon, which is proceeding at high temperature in electrical resistant furnaces. After riddance of fine crystalic nonreactive product, silicon carbide is crushed, milled, washed in water, megnetized and sieved on abrasive grains in size of F14 - F220.

2. Chemical compound:

- is made at grain F40
