Quartz tube
Diameter: 0.7～300mm
thick: 0.3～10mm
This is generalproduct manufactured by continuous drawing and continuous drawing method can use differentcharacteristics of the raw material to produce good appearance and dimensionclear quartz tube and clear quartz rod. OH content can be adjusted by heattreatment. This kind of product can be used for mercury lamp, halogen lamp electricheater, semiconductor materials, optical fiber parts and other applications.

Quartz glass properties：
1.resistant to elevated temperatures
The hardening temperature of quartz glass is about 1730℃.
2.Resistant to erosion
In addition to hydrofluoric acid, quartz glass is simply not and other acid materials attack chemical reaction, its acid resistance is 30 times ceramic, 150 times stainless steel, especially in low temperature under the chemical stability, is the rest of any engineering materials can not be compared.
3.Good thermal stability
The thermal shrinkage coefficient of quartz glass is very small, can undergo violent temperature change, quartz glass will be heated to 1100℃ or so, put in normal temperature water will not burst.
4.Good light transmittance
Quartz glass has good transmittance in all spectral bands from purple to red, with visible light transmittance of over 93%, especially in the ultraviolet spectrum, with the maximum transmittance of over 80%.
5.Good electrical insulation
The resistance value of quartz glass is commensurate with the ordinary glass 10,000 times, is an excellent electrical insulation material, even in the low temperature also has a good electrical performance.
