Fused quartz tubes and tubing are made by fusing or melting, naturally occurring quartz crystals. The crystals used are of a very high purity. This process takes place at 3632°F or 2000°C. This requires using high temperature furnace. Fused quartz tube and tubing is normally a transparent. The optical and thermal properties of fused quartz is far superior to those of other types of glass. This is due to its very high purity. Fused quartz is used in ultraviolet transmission, clear lens, and other optics for the ultraviolet spectrum. Quartz has low coefficient of thermal expansion. This makes it a useful material for precision mirror substrates. Thermocouple protection tubes are also made from fused quartz. Quartz protection tubes are excellent for molten precious metal applications.

Clear quartz tube is a special industrial technology  

Transparent quartz glass plate is offered in a wide variety of grades cut from various solid materials. It is used for instance to produce etch tanks or as windows and cover plates for various applications. Grades are primarily differentiated by the production route and the chemical impurity characteristics. Therefore, transparent quartz glass plates are divided into two larger groups: flame fused and electrically fused. In each group a variety of grades is available, each with individual advantages for specific applications.

Fused quartz glass plate is widely used for industry and science for its optical and mechanical properties. These properties make it resistant to chemicals, withstand high temperatures and thermal shock. It has a low thermal expansion and high transmission from UV 260nm to over 2 microns.

Vitreous silica is the generic term used to describe all types of silica glass with producers referring to the material as either fused quartz or as fused silica. Originally, these terms were used to distinguish between transparent and opaque grades of the material. Fused quartz products were those produced from quartz crystal to make transparent ware, and fused silica described products manufactured from sand into opaque ware. Today, however, advances in raw material beneficiation permit transparent fusions from sand as well as from crystal. Consequently if naturally occurring crystalline silica (sand or rock) is melted, the material is simply called fabricated quartz. When silicon dioxide is synthetically derived, however, the material is referred to as synthetic fused silica.

Quartz for photovoltaic and semiconductor is used in many facets of photovoltaic (PV) cell manufacturing, in light sources, reaction chambers, and tools used in the production of solar cells, thin films, and silicon wafers. The material's stability, chemical purity, transmissivity to light, and heat resistance has made quartz vital to the production of semiconductors.
