What is the difference between green silicon carbide and black silicon carbide?
Both black silicon carbide and green silicon carbide are made of quartz sand, petroleum coke and wood chips as raw materials through high-temperature smelting in a resistance furnace, but green silicon carbide needs to add industrial salt when smelting, and the smelting time is also higher than that of black silicon carbide. silicon.
Performance aspects of black silicon carbide and green silicon carbide:
The toughness of black silicon carbide is higher than that of green silicon carbide, and it is mainly used to process materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron, non-ferrous metals, etc.
Green silicon carbide has good self-sharpening, mainly used for processing cemented carbide, titanium alloy and optical glass, and also used for honing cylinder liners and precision grinding high-speed steel cutting tools and so on.
In terms of color:
The color of black silicon carbide is named after black gray; green silicon carbide is named after its color is green.
