Step 1: Isolate Silicon From Silica. Isolating silicon from silica is the first step in producing silicone. To achieve this, a large volume of quartz sand is heated to temperatures as high as 1800 degrees Celsius. Pure, isolated silicon is the result. Once it cools, manufacturers can grind it into fine powder.

Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ...
