Product Description

Silicon carbide Our exquisite collection boasts both black and green silicon carbide, each meticulously crafted with precision from high-quality materials. Black silicon carbide, an engineering marvel, is born from a perfect blend of quartz sand, petroleum coke, and premium silica, expertly smelted at soaring temperatures within a resistance furnace. This remarkable material showcases hardness between corundum and diamond, surpassing corundum in mechanical strength while retaining a sharp, crisp brittleness. On the other hand, green silicon carbide emerges from a similar meticulous process, combining petroleum coke and high-grade silica with the addition of salt, creating a product with comparable hardness and superior mechanical strength.

Black Silicon Carbide This extraordinary material is celebrated for its sharp brittleness and outstanding electrical and thermal conductivity, boasting a Knoop hardness rating between 3100-3280kg/mm². It is a vital asset in a myriad of industrial applications.

Green Silicon Carbide Regarded as a synthetic marvel, green silicon carbide is a brittle yet immensely strong carborundum with exceptional thermal conductivity. Its robustness remains unwavering even at temperatures reaching 1000ºC, outperforming Alumina by an impressive 7.5 times.

This silicon carbide variant stands out with its extreme hardness, achieving a formidable Mohs rating of 9.4 and 2600 Knoop, just behind CBN and B4C, making it a top choice for demanding applications.

Silicon carbide-based abrasives excel in processing materials such as cast iron, non-ferrous metals, rock, leather, rubber, and more. This versatile material is also extensively utilized as a refractory component and a crucial metallurgical additive.
