The key is to choose high-quality black silicon carbide and green silicon carbide with different purity and applications

1. Black silicon carbide contains about 98.5% SiC and has higher toughness than green silicon carbide. It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron, and non-ferrous metals. Green silicon carbide contains over 99% SiC and has good self sharpening properties. It is mostly used for processing hard alloys, titanium alloys, and optical glass, as well as for honing cylinder liners and precision grinding high-speed steel cutting tools.

2. In addition, there is a special variety of silicon carbide, which is cubic silicon carbide. It is a specially made yellow green crystal that is mostly used in the precision machining industry, such as bearing processing, with good micro machining effects.

Silicon carbide, due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, has many other uses besides being used as an abrasive. For example, by applying silicon carbide powder to the inner wall of a turbine impeller or cylinder block through special processes, its wear resistance can be improved and its service life can be extended by 1-2 times; Made of advanced refractory materials, it is heat-resistant, shock resistant, small in size, lightweight, and has high strength, with good energy-saving effects.

Silicon carbide has high hardness and excellent thermal conductivity. It is a semiconductor that can resist oxidation at high temperatures.
