Product Description

Silicon carbide Our Silicon Carbide collection shines with both Black Silicon Carbide and Green Silicon Carbide as its stars. Black Silicon Carbide emerges from the fusion of quartz sand, petroleum coke, and premium silica in high-temperature resistance furnaces, achieving a perfect balance of hardness between corundum and diamond. Its superior mechanical strength surpasses corundum, enhancing its brittle and sharp nature. Meanwhile, Green Silicon Carbide is crafted with petroleum coke and top-tier silica, with a touch of salt as an additive, also smelted at high temperatures. It matches the hardness of Black Silicon Carbide and boasts mechanical strength greater than corundum, ensuring performance excellence.

Black Silicon Carbide is prized for its brittle, sharp edges and exceptional electrical and thermal conductivity. The Knoop hardness of this superb material ranges from 3100 to 3280 kg/mm², showcasing its unmatched resilience.

Green Silicon Carbide is an advanced synthetic carborundum, delivering spectacular thermal conductivity and incredible strength, which remains unwavering even at temperatures soaring up to 1000ºC, outperforming Alumina by 7.5 times.

Green silicon carbide stands out with its remarkable hardness, reaching Mohs 9.4 (2600 Knoop), ranking only after the elite CBN and B4C, making it a top choice for demanding applications.

The exceptional abrasives derived from silicon carbide are perfect for efficiently working with cast iron, non-ferrous metals, rock, leather, and rubber. Its versatility extends to being an indispensable refractory material and a vital metallurgical additive.
