Making of fused silicaHeraeus

Because of the high temperature of the plasma, this process is best suited to produce fluorine doped fused silica. The achievable maximum content of fluorine in silica is a function of deposition temperature. There is a limit to the maximum fluorine content, because fluorine also etches away fused silica.

Glass making

1. Sand or Silica The main ingredient of glass making is Silica, which as a very high melting point of over 2,000 deg C. It is possible to make highly specialised products from just silica such as halogen lamps or one of the materials in fibre optic cables. This is because it has such a high melting point and is stronger than normal glass. 2.

Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
