Silica is the dioxide form of silicon (SiO 2) and occurs naturally in the form of quartz. While beach sand is also largely quartz, the most common raw material for electronic grade is high purity quartz rock. Ideally the silica has low concentrations of iron, aluminum and other metals. The silica is reduced (oxygen removed) through a reaction with carbon in the form of coal, charcoal and ...

Processes for Upgrading Metallurgical Grade Silicon to ...

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 ...
