Product Description

Black Silicon Carbide Power

Black silicon carbide micro powder is a non-metallic abrasive made from high-quality quartz sand, petroleum coke and other raw materials through high-temperature smelting. It exhibits exceptional properties including high hardness, outstanding wear resistance, thermal stability, excellent thermal conductivity, chemical inertness, and tunable electrical conductivity. 

With the continuous development of new material technologies, the performance optimization and application expansion of black silicon carbide are ongoing. In the future, it is expected to play an even more significant role in emerging fields such as semiconductor processing and new energy battery materials.

In terms of applications, black silicon carbide micropowder is widely used. It serves as an abrasive for manufacturing grinding tools, suitable for fine grinding, lapping and polishing of cast iron and non-metallic materials (e.g., glass, ceramics, stone). In the electronics industry, it is used for cutting and grinding semiconductor wafers,  Additionally, it can be added as a wear-resistant material to coatings, brake pads and other products to enhance their wear resistance.

Application:

•In the field of abrasives, it serves as an ideal material for bonded abrasives such as vitrified grinding wheels and resin grinding wheels, as well as coated abrasives like sandpaper.
•In metallurgy, due to its low nitrogen and sulfur contents, it can be used as an additive in steelmaking, a deoxidizer, and a solid fuel, and is applied in blast furnace production and steel recycling.
•In the refractory materials sector, with its high melting point, low coefficient of expansion, and other properties, it is used to manufacture furnace linings, fire bricks, and more.
•For sandblasting, polishing, and lapping operations, its high hardness and sharp grains make it suitable for handling hard materials.
•In wire sawing, precise powders are used for cutting silicon wafers.

•It can also be employed in the construction of anti-slip pavements, such as ship decks and airport runways. 
•Moreover, because of its high density and low porosity, black silicon carbide is suitable for high-performance advanced ceramics.
