Quartz/Fused Silica

Quartz is extremely pure and therefore has high working and melting temperatures.

Quartz/Fused SilicaIts optical and thermal properties make it superior to those of other glass materials due to its purity. Quartz and fused silica are ideal for semiconductor fabrication and laboratory equipment.


Our fused silica’s cross-linked, 3D structure delivers exceptional thermal shock resistance, UV transparency and near-zero thermal expansion.

We also supply industrial fused silica, a commercial grade of fused silica used in many sight glass applications, as well as UV-fused silica, which can be selected for a low content of inclusions and/or a high refractive index homogeneity if required.


Swift Glass supplies several types of quartz material manufacturers and brands, including:


  • Corning® 7980 is a very pure, non-crystalline silica glass. It features very low thermal expansion and excellent optical qualities, including very high transmission in the UV spectrum.
  • Blue Vycor® is made of 96% silica glass and is optimal for high temperature applications.  Due to its low coefficient of thermal expansion, Blue Vycor® also provides excellent shock resistance.
  • 1723 Aluminosilicate is  high temperature withstanding, very high pressure resistant  glass used in equipment for steam generating electrical power.


GE 124 is a very pure fused quartz, made from crystalline silica. GE 124 is very similar to fused silica, with the exception of less transmission in the UV spectrum and much lower OH content. Other features besides its purity include excellent thermal properties and high resistance to chemicals.

TSC-3 Quartz

Standard quartz glass of high purity and very low bubble content for semiconductor manufacturing equipment, especially suitable for etch systems.
