Product description:

In the production of non-ferrous metals, charcoal is often used as a surface flux. When the non-ferrous metals are melted, the surface flux forms a protective layer on the surface of the molten metal to separate the metal from the gas medium, which can reduce the splash loss of the molten metal and reduce the melting The saturation of the gas in the substance.

A large amount of charcoal is also used in the production of crystalline silicon, and the charcoal used in the production of crystalline silicon should not contain raw charcoal heads and excessive ash.
