Product Description

Silicon carbide Our exquisite collection features both black and green silicon carbide, each crafted with precision and the finest materials. Black silicon carbide, a marvel of engineering, is meticulously produced from select quartz sand and premium petroleum coke, smelted at high temperatures in a resistance furnace to achieve unparalleled quality. This extraordinary material boasts a hardness that nestles perfectly between corundum and diamond, outshining corundum in mechanical strength while presenting a distinct, sharp brittleness. On the other hand, green silicon carbide is born from the same painstaking process, with the addition of salt, resulting in a product of similar hardness, yet boasting superior mechanical strength.

Black Silicon Carbide This remarkable material is celebrated for its sharp brittleness and outstanding electrical and thermal conductivity. With a Knoop hardness rating of 3100-3280kg/mm², it is an indispensable asset across a myriad of industrial applications.

Green Silicon Carbide Green silicon carbide, a synthetic marvel, is a brittle yet incredibly strong carborundum with exceptional thermal conductivity. Its unrivaled strength persists even at 1000ºC, making it 7.5 times more effective than Alumina.

This variant of silicon carbide is renowned for its extreme hardness, boasting a formidable Mohs rating of 9.4 and a Knoop hardness of 2600. Positioned just behind CBN and B4C, it is the prime choice for the most demanding applications.

Silicon carbide-based abrasives excel in processing a wide array of materials such as cast iron, non-ferrous metals, rock, leather, and rubber. Moreover, this versatile material is extensively utilized as a refractory component and an essential metallurgical additive.
