98% content Black silicon carbide fraction 0.5-1mm

Black silicon carbide 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 shape and evenly distributed. The black silicon carbide powder produced by pickling purification process, which helps the sintered ceramics maintain better sintered density and bending strength.

Product Feature of 98% content Black silicon carbide fraction 0.5-1mm

1. 1. Black silicon carbide has strong anti-oxidation ability. It can maintain the stability of chemical performance even at high temperature.

   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.
