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

Clear quartz tube is a special industrial technology glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physicale property of high purity and high temperature resistance.

The clear tube that protects a UV lamp is called a sleeve and is made of quartz. The UV clear quartz sleeve is an essential part of any UV water filtration

UV block quartz tube is clear fused quartz glass doped with cerium to block ultraviolet. This glass block all vacuum ultraviolet, nearly all UV-C, UV-B and

Ozone free quartz tube is used for making "Ozone free" UV sterilizing lamp. It is transparent and cut surface is slight purple. Doped with Ti, it can prevent radiation of high-density UV rays but generate no ozone. Spectrum transmission at 185 nm is 0 and no ozone generated. UV transmission at 254 nm is more than 90%. The UV sterilizing lamps made by electric melting quartz tube have much longer life than fused quartz tube.

Fused quartz rod is available from our stock. All rods supplied in 4 ft. lengths. Longer lengths available upon request and subject to minimum 4 ft. quantities. Larger diameters available for quotation. The single-component glass consists solely of silica (SiO2). Through its unique combination of thermal, mechanical and optical properties, fused quartz is one of the most important materials for industry and research. Through its unique combination of thermal, mechanical and optical properties, fused quartz is one of the most important materials for industry and research. For the semiconductor an solar industries, fused quartz is used in high temperature processes because of its high softening point, low thermal expansion and excellent thermal shock resistance.

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.
