Introduction to Black silicon carbide

Black silicon carbide is a non-metallic ceramic material composed of carbon and silicon elements. Black silicon carbide has very high hardness, belonging to Mohs hardness level 9.5, second only to diamond and cubic boron nitride.

The high hardness of silicon carbide gives it excellent wear resistance and corrosion resistance. It is widely used in the fields of abrasives, wear-resistant materials and cutting tools.

The silicon carbide material produced by Zhen’an Metallurgical Materials is calcined in a high-power resistance furnace, with a smelting time of more than 200 hours. High-purity, well-crystallized first-grade silicon carbide blocks are used as raw materials.

Types Of Black silicon carbide

Black silicon carbide properties

Black silicon carbide has extremely high hardness, with a Mohs hardness of 9.5, second only to diamond and cubic boron nitride. This makes it excellent in wear, cutting and abrasive applications.

Due to its high hardness, black silicon carbide has excellent wear resistance and is able to maintain stable performance in high friction and high stress environments. Therefore, it is widely used in fields such as abrasives, grinding wheels, grinding tools and cutting tools.

Black silicon carbide has a high melting point (approximately 2700°C) and can maintain stable performance in high temperature environments. It has important applications in the fields of refractory materials, high-temperature ceramics and stoves.

Black silicon carbide has good thermal conductivity and can dissipate heat efficiently. This makes it play an important role in the field of thermal management, heat sinks, heat sinks and other applications.

Black silicon carbide is a semiconductor material with high resistivity and low electrical conductivity. This makes it widely used in fields such as power electronics, semiconductor devices, and electromagnetic equipment.

The surface micro-nano structure of black silicon carbide gives it low reflectivity and good light absorption properties. This gives it potential applications in areas such as solar cells, lasers and optical coatings.

Application of Black si carbide

For Abrasives and refractory materials:

1.Improve the heat resistance, wear resistance and oxidation resistance in refractory material and power metallurgy industry.

2.Basic raw material that high polymer of organic silicon formatting.

3.Iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel hardenability.

4.It is used in high-temperature material production in order to manufacture enamels and pottery and in producing ultra-pure silicon wafers.
