A step up along the silicon refining process—with purity ranges anywhere from 99-99.99%.
Chemical grade silicon is used to make silicones, including sealants and lubricants, silanes, such as coupling agents, and fumed silica, as a desiccant and thickening agent.

The production of chemical grade silicon metal begins with the refining process of silica within quartz rock or sand.

This is followed by a carbothermic reduction of silica that occurs in an arc furnace to produce metallurgical grade silicon. This is then further refined through a hydro-metallurgical process to produce chemical-grade silicon. The industrial uses of chemical grade silicon are vast.

Polymers are macromolecules that are composed of repeating subunits.

The repetition of subunits produces significant strength and flexibility within the molecule, meaning polymers have highly adaptable industrial uses. The flexibility of polymers is further enhanced because they can exist in both natural and synthetic forms.


Most of the applications for chemical-grade silicon centers around the production of silicone polymers. The photovoltaic industry is another primary user of silicon and silicones.
