Product Description

Silicon carbide Our exquisite collection includes both black and green silicon carbide, each crafted with precision and high-quality materials. Black silicon carbide, a marvel of engineering, is produced from quartz sand, petroleum coke, and premium silica, expertly smelted at high temperatures in a resistance furnace. This exceptional material boasts hardness between corundum and diamond, surpassing corundum in mechanical strength, while maintaining a crisp, sharp brittleness. In contrast, green silicon carbide emerges from the same meticulous process, utilizing petroleum coke and high-grade silica with the addition of salt, resulting in a product of comparable hardness and superior mechanical strength.

Black Silicon Carbide This remarkable material is renowned for its sharp brittleness and exceptional electrical and thermal conductivity, with a Knoop hardness rating between 3100-3280kg/mm², making it an indispensable asset in numerous industrial applications.

Green Silicon Carbide Known as a synthetic wonder, green silicon carbide is a brittle yet immensely strong carborundum with extraordinary thermal conductivity. Its strength remains unyielding even at 1000ºC, outperforming Alumina by 7.5 times.

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

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