Green silicon carbide series: Green silicon carbide series: Green silicon carbide crystalline block is got from the main raw material of petroleum coke and high-quality silica, add salt as an additive smelted through the high-temperature resistance furnace. The hardness is between corundum and diamond, the mechanical strength is higher than corundum’s, crisp performance and sharp. Green silicon carbide powder: The silicon carbide graded sand is crushed classificated through the airflow, then chemical treatment, get the powder series. Uses: multi-purpose abrasives grinding materials such as grinding wheel, sanding paper, sanding belt etc, cutting abrasives, crystal, refractories, etc. High-purity single crystal silicon carbide materials High-purity single crystal silicon carbide materials: Rise the purity up to higher than 99.9%through the special chemical treatment, after the special treatment, the silicon carbide becomes the high-quality raw materials for the growth of SiC single crystal
