1. Product Introduction of Black silicon carbide particle

Black silicon carbide particle is the raw material for sintered silicon carbide ceramics. It has excellent properties such as high strength, high hardness, high thermal conductivity, good chemical corrosion resistance, and good thermal shock resistance. Sintered silicon carbide ceramics are often used in thermal power desulfurization systems, chemical anti-corrosion and wear-resistant parts, and other anti-corrosion and wear-resistant fields. For silicon carbide ceramic manufacturing, the black silicon carbide particle should be of high SiC purity and particles consistency. The black silicon carbide particles and powder produced by Haixu Abrasives are made of 98% silicon carbide A-grade blocks, which are processed by the ball milling process. The grains are round in shape and evenly distributed. The black silicon carbide powder is produced by the pickling purification process, which helps the sintered ceramics maintain better-sintered density and bending strength.

 

The properties of black silicon carbide particles include:

  1. Black silicon carbide has a strong anti-oxidation ability. It can maintain the stability of chemical performance even at high temperatures.
  2. Strong toughness, high bending strength, strong compressive ability under high temperature.
  3. The density of black silicon carbide is lower than alumina, and the sintered silicon carbide ceramics are lighter than corundum ceramic parts.
  4. Low thermal expansion coefficient and low thermal conductivity. Stable thermal performance.
  5. High wear resistance, Mohs hardness 9.2-9.3, Vickers hardness 2200. It is higher than corundum and lower than diamond.
  6. High purity, low free carbon, iron, and other impurities, which is beneficial to the sintering of silicon carbide ceramics.

8. FAQ:

Q: Are you a manufacturer?

A: Yes, Our factory was established in 1999. We have plants of black silicon carbide and green silicon carbide.

Q: What are the difference between the FEPA, JIS, USS grit sizes?

A: FEPA grit size is according to FEPA European standard. JIS grit size is according to the Japanese JIS standard which is of more grits than the FEPA standard, especially for micro powder. USS is according to ANSI USA standard whose sieving to Tyler mesh.

Q: Are the silicon carbide material from you is reclaimed material?

A: No. We only produce A-grade silicon carbide produced from high-quality melted SiC blocks.

Q: Is there any restriction to export silicon carbide from China?
