Processes for Upgrading Metallurgical Grade …

Introduction Metallurgical grade silicon (MG-Si) is the initial material to produce pure silicon for photovoltaic and electronics applications. It is commercially produced through the reduction of silicon oxide (quartz) with carbon in submerged arc furnaces [1]. An idealized form for the process can be written as: SiO 2 + 2C = Si+ 2CO (g) (1) The produced MG-Si is not pure, typically 99.0wt ...

Silicon (Si) for solar cells: how is it produced ...

Industrial grade silicon manufacturing process. At very high temperatures (often in excess of 2000 °C or 3600 °F), the carbon displaces oxygen from the silicon compound, forms carbon monoxide and leaves Si behind in a molten state. This liquid Si is collected at the bottom of the furnace, drained and cooled. As this silicon is only about 98% pure, it is called industrial grade silicon (or ...
