What Are The Advantages Of Quartz Glass Tubes?
Quartz glass tube is a special industrial technical glass made of silica,which has a series of excellent physical and chemical properties such as higher hardness and transparency than normal glass tubes; and the quartz tube is resistant to high temperature, abrasion resistance, and it has a stronger ability to soothe the reaction. The components of the normal soda-lime glass tube is mainly sodium silicate, silicon dioxide and calcium silicate , and its hardness, transparency, high temperature resistance, and wear resistance are much worse than quartz glass tube.
* Fused Quartz Tubes/Silica Tubes:
* Specification:
* Application:
1. Widely used in chemistry, machinery, laser, optical instrument, Scientific research laboratory, Electronics,semiconductor industry etc.
2. Our quartz ampoules features high purity (>99.99%), good physical and chemical properties, tight tolerances, and low -OH content. The rods are used in a variety of applications by our customers.
* Properties:
1.High purity , SiO2> 99.99%.
2.Strong Hardness, Can reach Morse level 7.
3.High light transmission more than 85%.
4.High temperature resistance, can work under 1200°C continuously,
and in short time can even work under 1500°C.
5.Electric insulation, it is 10000 times of usual glass.
6.Acid and Alkali resistance
7.Excellent thermal shock stability,Small thermal expansion coefficient,it is only 5.5×10-7/ºC
8.Health care and environmental protection
9.Any dimension can be made.
