How to distinguish silicon carbide powder

Silicon carbide powder is used in the abrasive tool profession. Its quality will also determine the quality after the application of abrasive tools. If you know how to distinguish the quality of silicon carbide powder, you can choose products with better quality for application, so that the quality of abrasive tools will be improved to a certain extent.

The shape of silicon carbide powder is powdery particles, green, crystal structure, high hardness, strong cutting ability, stable chemical quality and good thermal conductivity.

Method 1: the particle analyzer measures the coefficient of particle shape accurately. It is a useful method to detect the cutting efficiency and cutting quality of silicon carbide.

Method 2: resistance method particle analysis uses resistance method particle analyzer to measure the particle size of silicon carbide, which can effectively distinguish the cleavage of silicon carbide and has high detection efficiency.

Method 3. The atomic absorption detection method can detect the content of silicon and judge the hardness of silicon carbide. The detection value is more accurate.

Generally, the common and commonly used silicon carbide powder on the market includes black silicon carbide powder and green silicon carbide powder.

Black silicon carbide powder is made of quartz sand, stone tar and high-quality silica through high-temperature practice in resistance furnace;

Silicon carbide powder is made of quartz sand, stone tar, high-quality silica and industrial salt as reactants and accelerators in the resistance furnace. The product is colored, so it is named silicon carbide powder.

However, if the function is the same, why so many colors? Is it for different environmental color needs? Of course not. First of all, in addition to color differences, silicon carbide micro powder has good self sharpening and black silicon carbide micro powder has good resistance. We can use them in different operations through their different characteristics.

The texture of SiC powder is purer than that of black SiC powder, and its hardness is higher than that of black SiC powder. Besides its grinding purpose is the same as that of black SiC powder, it is more suitable for fine grinding of data, such as grinding threads, grinding measuring tools, etc. in grinding data, it is more widely used for workpieces of cemented carbide and diamond products.
