A process of removing impurities and, in par ticular, Aluminum and calcium, contained in the silicioy in Alloys of silicon.

摘要

Procedure for the removal of impurities, in particular Calcium Aluminium contained in Silicon and Silicon based Alloys. Available Silicon or Silicon Alloy Liquid Laundry in a Spoon.In the lower part of the Spoon, Oxygen is injected through the central Tube, a double Flow Nozzle Protector and a Fluid, such as carbon monoxide and Dioxide, argon, Helium, water vapor or Hydrocarbon gaseous or liquid through the annular Space of the nozzle, is subject to agitac Silicon ion mass.Simultaneously, or following the Injection of Oxygen, can be injected through the tube axial Nozzle a substance containing at least one Active Atom can be Oxygen, Fluorine or chlorine, as a sulfate or carbonate and Alkaline Earth. Purified Silicon is used for adding the Aluminum and Magnetic sheets with low losses.
