What differences between green sic and black silicon carbide?
Chemical composition:
Black silicon carbide (SiC) contains about 98.5% SiC and has a high purity.
Green silicon carbide contains more than 99% SiC and has a higher purity.
Physical properties: Color and appearance
Black silicon carbide is a black hexagonal crystal, and green sic is a green translucent body.
Hardness: The hardness of black silicon carbide is between corundum and diamond, and the hardness and purity of green sic are higher than black silicon carbide.
Mechanical strength: The mechanical strength of black silicon carbide is higher than that of corundum, and the mechanical strength of green sic is higher than that of black silicon carbide.
Other properties: Black silicon carbide is brittle and sharp, and green silicon carbide has good self-sharpening properties.
Application areas Application of black silicon carbide:
Used to produce products with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. Used in polishing and grinding materials, refractory materials, metallurgical mineral processing and other industries.
