Melting is effected at approximately 2200 °C (4000 °F) using either an electrically heated furnace (electrically fused) or a gas/oxygen-fuelled furnace (flame-fused). Fused silica can be made from almost any silicon-rich chemical precursor, usually using a continuous process which involves flame oxidation of volatile silicon compounds to silicon dioxide, and thermal fusion of the resulting dust (although alternative processes are used). This results in a transparent glass with an ultra-h… WebIts refractive index varies from 1.55 to 1.40 (for its transparent range: 160nm to 3000nm). Because fused silica is optically stable and consistent, many use it as a reference or standard for spectroscopic measurements. The details of its refractive index temperature dependence are also well studied.
