Differences between black silicon carbide and green silicon carbide:
First, the color is different
Black silicon carbide is black color and green silicon carbide is green color.
Secondly,the raw material is a litter different.
The main raw material is silica sands and petroleum coke,but when produce green silicon carbide,salt will be added during smelting.
Thirdly,the purity is a little different
The purity of green silicon carbide(more than 98.6%) is a little higher than black silicon carbide(more than 98.0%)
Fourthly,unit price
The cost of green silicon carbide is higher,that is to say unit price of green silicon carbide is higher than black silicon carbide
