Difference Between Black Silicon Carbide and Green Silicon Carbide

Author:Jinlin corundumTo update: 2016-10-11

According to our previous written by the main use of silicon carbide, we have the overview of the use of silicon carbide, however, silicon carbide is divided into green silicon carbide black silicon carbide, and I want to have seen the difference between the black fused alumina and black silicon carbide may have a certain knowledge of black silicon carbide, but we often when buy, don’t know whether need to purchase a black silicon carbide or green silicon carbide, today I company with the difference between black silicon carbide and green silicon carbide as a simple for you.
We all know that silicon carbide in the modern daily life and industrial manufacturing and high-tech products such as: chip, military, aviation and other fields is widely used. Although the black silicon carbide and green silicon carbide is a kind of silicon carbide. But their use and price is not the same.
Black silicon carbide is quartz sand, petroleum coke and high-quality silica as the main raw material, through the resistance furnace made of high temperature smelting. Its hardness is between brown fused alumina and emery, mechanical strength is higher than brown fused alumina, brittle and sharp, relatively green silicon carbide price is cheaper.

Green silicon carbide production process and the same black silicon carbide, but the use of raw materials of higher purity requirements, but also in the resistance furnace in the 2200 ° C about the formation of high temperature, translucent, its content than black silicon carbide, physical properties And black silicon carbide similar, but the performance is slightly brittle black silicon carbide, but also has good thermal conductivity and semiconductor properties. Its hardness between the brown fused alumina and emery, mechanical strength is higher than the brown fused alumina, relatively black silicon carbide price is more expensive.
Silicon carbide applications and features:
Black silicon carbide containing about 95% of SiC, its toughness is higher than the green silicon carbide, mostly used for processing low tensile strength materials such as glass, ceramics, stone, refractories, cast iron and nonferrous metals.
② Green silicon carbide containing about 97% or more of SiC, self-sharpening, mostly for processing carbide, titanium and optical glass, but also for grinding cylinder liner and high-speed steel grinding tool.
Shizui Mountain Jinlin Fused Alumina Refractories Co., Ltd. is a diversified production plant, set the development, production, sales and service in one. The company mainly produces fused alumina products, brown fused alumina, white fused alumina, silicon carbide, bauxite, alumina ball, garnet, alumina powder, zircon sand, castable and other products specializing in the production and processing company, with a complete and scientific quality management system.
These are my company summary of the black silicon carbide and green silicon carbide difference, I hope you can help. If necessary, please contact us. Thank you for reading, please continue to pay attention to our website!
