Black carborundum
1. Descriptation for black carborundum:
Black silicon carbide is made from quartz sand and smokeless acetylene as the mainraw material.it is made via light resistance from hydrometallurgical,it is black opaque body hexagonal crystal and MOHS -hardness in the 9.15,which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.
2.Usage for black carborundum:
1.Sic processed by low-intensity metal and non metallic and also can be used in fire-resisting materials and the electronic industry
2.Colored metal .iron and steel industy .constructing materials and ceramic .Energy-saving
3.Usage:It is the important raw materials of high refractories manufacturing ,high-temperature ceramics,body heat resistance, abrasives and recrystallized silicon carbide.
