sand silicon production line

Silica (Sio2)

Silica (SiO 2) is a starting material for silicon, which is sand or quartz.The removal of oxygen or reducing silica to silicon is a key processing step in silicon production. Fig. 3.3 shows the different methods used to reduce the silica to silicon. MG-Si is the starting material to produce pure silicon for PV and electronics applications.
