5 Metallurgical Silicon Production

Metallurgical Silicon Production

Posted on January 22, 2011 by team


The Silicium factory in Kazakhstan produces metallurgical silicon in a special way using special ore heat-treating furnaces. This is one of the biggest factories in the whole country and the only one specializing in this field.

Silicon is the second most plentiful element of the Earth’s crust after oxygen. It is commonly found in the combinations with silica and silicate. Pure silicon is used in various semiconductor devices and metallurgy.

2 types of products are made here: metal silicon (used in aluminium and chemical fields) and silicon dust (used in production of extra-strong dry building mixtures).

Silicon of technical purity (up to 99.9%) is made at a temperature of 1800 C inside the ore heat-treating furnaces (the main admixtures are carbon and metals).

The fireproof furnace is a kind of a round steel outer cover with a bottom lined up with fire bricks.

    Interesting that born out of that huge industrial process is the tiny little chip that powers every gadget we own.

    It certainly looks like dangerous work. I wonder what it smells like in there? Interesting post and video. Thanks.
