silicon powder

Characteristics:

Silicon metal is also called industrial silicon or crystalline silicon . It is dark gray . Its point is high , heat performance, excellent antioxidation. The usual size of industrial silicon are in the range of 10-100mm or 2-25mm.

Use :

 The silicon metal was manufactured with carbon type reducing agents while silica being melting, it is mainly used in production of alloys especially aluminium alloys poly-crstalline silicon and organic silicon materials .
