Those gases could then be used to process sand into pure silicon and to obtain silanes. Another procedure, widely used today, is to purify silicon dioxide using heat from coal, but Plichta has now developed a new process that would use tar, pitch and bitumen as well as aluminium silicate to produce pure silicon and silanes at a very low cost.
