Quartz glass | Synthetic fused silica with optical .Deze pagina vertalen

    Unlike Fused Silica, these quartz glass grades are made by melting natural quartz instead of high purity synthetic quartz, and they contain significantly more contaminants. Hence, these materials cannot offer such a high material quality and homogeneity as Fused Silica, and they are typically used for less demanding applications.

    Crystal quartz (SiO2) and Fused Silica

    If the silicon dioxide is synthetically derived, the material is often called Fused Silica. Fused Quartz is very pure, has a high chemical resistance, good thermal shock resistance and is very strong in compression. The low thermal expansion coefficient makes it ideal for mirrors and optical flats. It is used for viewing windows, being transparent to wavelengths from around 0.2 to 3.5 µm ...
