High Purity 98.5% Sic Black silicon carbide sand f24

High Purity 98.5% Sic Black silicon carbide sand f24
Black SiC is produces in electrical internal resistance furnaces from high purity silica sands petroleum coke,its combination of being very hard and sharp makes it a very aggressive abrasive.
Mainly Applications
-Bonded Abrasives and Coated abrasives
-Blasting,surface Treatment,Rust Removal
-Wet and dry blast media,grinding and polishing etc
-Floor/Wall laminates,Wear-resistant
-Ceramic products: Ceramic and Tiles,Ceramic filter plate,ceramic membrane etc
-Teflon painting etc
– Heat insulating material  
-Grinding wheels,Cup wheels,Whetstone,polishing pads etc
-Used for crucibles, parts for kiln burning, mechanical seals, and parts materials to produce semiconductors
