Silica

The name Silica covers a range of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. Silica exists in ten different crystalline forms. By far the most common of these is quartz. It is hard, chemically inert and has a high melting point. Silica is sold as sand and processed for multiple uses.

Making of fused quartz and fused silica

Precise production and refinement of precursors leads to exceptionally high purity and the resulting fused silica has a very low metallic impurity content. As the production process involves chemical vapors (silicon containing precursors), it is called chemical vapor deposition (CVD).
