Black Silicon Carbide /Carborundum With SiC 98.5% Min. (Refractory Grade)
1.Production description:
Black 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.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.
