Black Silicon Carbide Powder

Introduction of Black Silicon Carbide Powder

Black silicon carbide powder products are mainly used in the manufacture of refractory products, ceramic foam industry, solar silicon chip cutting, crystal cutting and grinding, engine manufacturing, special coating industry, plastic product modification, desulfurization, power supply, environmental protection industry, etc. It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.

Black silicon carbide powder is a man made mineral with a high thermal conductivity rating of 100 W/m-K. It is extremely hard, around a Mohs 9.1 or 2550 Knoop. It has high strength at elevated temperatures. For example, at 1000oC, SiC is 7.5 times stronger than Al203 (aluminum oxide). Black silicon carbide powder will contain some free silicon and carbon and thus is not as pure as green silicon carbide. Black silicon carbide powder will range in purity from 97-99% pure, depending on grit size. Green silicon carbide powder is made from Silica sand and coke, and is extremely pure. Hexagonally shaped, it breaks into very sharp particles. Our green SiC is 99.5% pure.

Green silicon carbide powder is harder than black silicon carbide powder, coming in at a 9.4 Mohs and 2600 on the Knoop scale. Green is often the media of choice when it comes wire sawing. The micronization process of manufacturing our green silicon carbide is controlled by a computer. Then the material is water classified/separated - this produces a very tight particle size distribution, as well as a reduction in fines, as preferred for accurate wire sawing applications. Unless your application requires an extremely pure silicon carbide, by default, black silicon carbide is preferred due to its more economic pricing.

Application of Black Silicon Carbide Powder

Black silicon carbide powder is an important refractory material widely used in the metallurgical and steelmaking industries. It has many superior properties, such as high temperature resistance, high strength, and resistance to chemical attack, which makes it an indispensable material in these industries.

First of all, black silicon carbide powder is widely used in the metallurgical industry. In the metallurgical process, high temperatures and strong chemical reactions can cause loss and wear of many materials, and the high temperature resistance of black silicon carbide powder can effectively alleviate this situation. At the same time, it also has excellent corrosion resistance and can work stably in high-temperature acid and alkali environments, thereby better protecting industrial equipment.

Secondly, in the steelmaking industry, black silicon carbide powder also plays an important role. In the steel production process, black silicon carbide powder can not only increase furnace temperature and heat conduction, promote the melting and flow of metal, but also reduce the oxygen content in steel and improve the quality and purity of steel, thus improving steel production efficiency and product quality.

In addition, black silicon carbide powder also has good electrical and thermal conductivity and is widely used in electrolytic aluminum and semiconductor industries. At the same time, the high strength and compressive resistance of black silicon carbide powder also make it an important raw material for manufacturing ceramics and high-strength alloys.

In short, black silicon carbide powder is widely used in the metallurgical and steelmaking industries, and its excellent properties provide strong support for the development of these industries. With the continuous advancement of technology and the increase in market demand, the application prospects of black silicon carbide powder will become broader.
