Fused quartz, fused silica or quartz glass is a glass consisting of almost pure silica (silicon dioxide, SiO 2) in amorphous (non-crystalline) form.

Silica glass is used where high service temperature, very high thermal shock resistance, high chemical durability, very low electrical conductivity, and good ultraviolet transparency are desired.… Read More

Silica glass has excellent transmission characteristics in a wide range of wavelengths, covering not only the visible range, but ultraviolet and infrared. Silica glass is composed of SiO 2 only, and contains very little amounts of metallic impurity.

Fused silica is essential for optical components, dielectric coatings, and fiber optics. UV- and IR-grade fused silica are available for special applications.

Sep 29, 2022 · Silica is a pure glass that is made up of SiO2. In commercial glasses, SiO2 is used, and other dopants are used to lower the melting temperature and improve the optical, thermal, and mechanical properties. It is also known as …

Feb 16, 2022 · Silicon glass – also called quartz or silica, is a type of premium glass made almost exclusively of pure silica. Silicon dioxide (SiO 2) accounts for as much as 99.9% of the raw material weight and determines the utility value of the material.

Silica glass distinguishes itself by its extremely small thermal expansion. In type III glass, dissolved water enhances dilation by about 5% from 0 to 100°C [Hetherington and Jack, 1962]. The effect extends to higher temperatures.

In the amorphous form, silica glass has become a prototype system for understanding the disordered state. The study of silica glass under high pressure is particularly important and challenging as it has been used as a zeroth order model of silicate magma in the earth's interior.

Corning supplied fused silica for ultrasonic delay lines used by the United States military to detect Soviet missiles. This became the first commercial application for fused silica.

Apr 15, 2020 · We stock a wide range of fused silica and quartz glasses from a variety of manufacturers, each of which offers unique advantages. For example, our fused silica demonstrates a cross-linked, three-dimensional structure that results in high thermal shock resistance, UV and IR transparency, and near-zero thermal expansion.
