silicon carbide powder/polishing and Engineering Ceramic/silicon carbide powder

   silicon carbide powder for polishing and Engineering Ceramic    1.For polishing and Engineering Ceramic 2.Sic:99% min 3.GB FEPA JIS ISO standard 4,Manufacturer     1.Production description: Silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synathetic diamond. Mechanical intensity of it is hig-her than fused alumina.it is brittle and sharp and has electrical and heat conductivity in some degree. 2. silicon carbide powder APPLICATION: *Cleaning, descaling, coating and contamination removali etching and surface preparation of ferrous and non ferrous metallic parts prior to rework, painting, coating, anodizing and powder coating. *Removal of thermal metal spray and carbon deposits from jet and gas engine components and turbochargers prior to rebuild, anodizing and thermal metal spray. *Decorative glass, stone, metal and wood etching and carving. 3.Chemical Analysis

4.Advantages 1. Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities. 2. Good hardness, longer life. 3. Chemical washed and water washed, good cleanness. 4. Special treated products get higher purity, better toughness, and better grinding effect.
