Product Description


Black silicon carbide /carborundum powder 320# 400# 500# 600# 700# 800#
Black silicon carbide F320 is an artificial abrasive made of carbonaceous materials and siliceous materials through high-temperature smelting in a large resistance furnace. The carbonaceous material is petroleum coke or coal coke. And the siliceous material always goes quartz sand. At the same time, the smelting process will also add wood chips, salt and other additives.
The purity of the silicon carbide of the A-grade black silicon carbide is more than 98%. The color is shiny, and the reflection shows multicolored colors. Generally, the higher the purity of silicon carbide, the better its physical and chemical properties. The hardness of black silicon carbide is slightly lower than that of green silicon carbide, with a Mohs hardness of 9.2-9.3. Haixu black silicon carbide powder is produced by crushing, washing, screening, magnetic separation, suspension treated processes. It has the characteristics of high purity, high cleanliness, even particle size distribution,high packing density, and low impurities.



Product feature


1. Very clean with few impurities such as free carbon,etc.
2. High hardness, retaining hardness and high wear resistance.
3. Excellent thermal shock resistance with high thermal conductivity and low linear thermal expansion.
4. Good particle distribution with narrow particle range.
5. Good ability to withstand the strongest alkalis and acids.
