How to judge the quality of green silicon carbide？

Like most abrasive products, green silicon carbide products are also based on the content of their main ingredients to determine the quality and price. The accurate judgment of the quality of silicon carbide must be laboratory chemical testing, and most manufacturers who need to use green silicon carbide do not necessarily have this experimental condition. If you want to simply judge the quality of purchased green silicon carbide, you can only use the actual use effect. Judging, this may cause unnecessary losses due to unqualified purchased products.
The editor here will introduce you a few simple ways to distinguish whether green silicon carbide is qualified, for reference only:
First of all, look at the hardness. Green silicon carbide is commonly called emery, and it is just a wordless difference from diamond. The high hardness of green silicon carbide has been tested in practice, and it is not a false name. High-quality green silicon carbide can directly cut glass, even harder workpieces.
Detect the carbon content, put the green silicon carbide powder or block particles in the container, add water and shake for a while, observe the degree of blackening of the water, the darker the green silicon carbide, the higher the carbon content, and the relative SiC content The lower.
