Quick Overview

Surface treatment abrasive, high quality black silicon carbide
SKU: Black silicon carbide


Non-metallic abrasive-Black silicon carbide

Black silicon carbide is made of quartz sand, stone tar or anthracite as the main raw material. It is smelted by high temperature resistivity. Its hardness is between corundum and diamond. Its mechanical strength is higher than that of corundum. It is brittle and sharp. Has a certain conductivity and thermal conductivity. It is used to make abrasive tools suitable for processing metal and non-metal materials with low tensile strength. Such as gray cast iron, non-ferrous metals, stone, leather, rubber and so on. Also widely used in refractory materials, metallurgical additives.


1. Large furnace smelting, long smelting time, sufficient crystallization, large crystal particles, high purity and less impurities;

2. High strength and good durability;

3. After pickling and washing with acid, the cleanliness is good;

4. The specially processed high-purity product has higher strength and stronger grinding ability.
