Product Description

Silicon carbide Our exquisite collection proudly showcases both black and green silicon carbide, each meticulously crafted with precision and the finest quality materials. Black silicon carbide, a true marvel of engineering excellence, is expertly produced from quartz sand, petroleum coke, and premium silica, all skillfully smelted at high temperatures within a resistance furnace. This exceptional material holds a hardness ranking between corundum and diamond, surpassing corundum with its superior mechanical strength, while retaining a crisp, sharp brittleness. In contrast, green silicon carbide is derived from the same meticulous process, incorporating petroleum coke and high-grade silica with an added touch of salt, resulting in a product of comparable hardness yet offering greater mechanical strength.

Black Silicon Carbide Renowned for its sharp brittleness and exceptional electrical and thermal conductivity, this remarkable material showcases a Knoop hardness rating of 3100-3280kg/mm², establishing it as an indispensable asset across numerous industrial applications.

Green Silicon Carbide Regarded as a synthetic wonder, green silicon carbide is a brittle yet extraordinarily strong carborundum, boasting outstanding thermal conductivity. Its resilient strength remains unyielding even at soaring temperatures of 1000ºC, outperforming Alumina by an impressive 7.5 times.

This variant of silicon carbide is distinguished by its extreme hardness, ranking a formidable Mohs 9.4 and 2600 Knoop, standing just behind CBN and B4C, making it a top choice for the most demanding applications.

Silicon carbide-based abrasives are unparalleled in processing cast iron, non-ferrous metals, rock, leather, rubber, and beyond. Additionally, this versatile material is extensively utilized as a key refractory component and a crucial metallurgical additive.
