Differences between 97 Silicon and Common Grades of Silicon Metal
Difference in Purity
97 Silicon:
The silicon content is about 97%.
Common Grades of Silicon Metal:
The silicon content is generally above 99%.
Differences in applications
97 silicon:
Due to its lower purity, 97 silicon is mainly used in the low-end market, such as as as a substitute for recycled silicon, and is suitable for some applications that do not require high purity.
Common Grades of Silicon Metal:
They have high purity and a wider range of applications, suitable for high-end markets and high demand fields.
Differences in production processes
97 silicon:
It is usually obtained by recycling silicon wafer cutting waste silicon sludge and smelting it in a medium frequency furnace, and belongs to a type of regenerated silicon.
Common Grades of Silicon Metal:
They are obtained by smelting raw materials such as silica and petroleum coke in an electric furnace. The production process is relatively complex and suitable for high-purity production.
