Product Introduction

• Black silicon carbide is produced in an electric-resistance type furnace through fusing quarts sand and petroleum coke and high quality silica with high temperature. Its hardness is between fused alumina and diamond's. 
• higher mechanical intensity than fused. 
• It is brittle and sharp and has electrical and heat conductivity in some degree. Black silicon carbide, metallic, sic≥95%, stronger than green silicon carbide but softer than green silicon carbide, is mainly used for grinding of cast iron and non-metallic materials.
