Products Description




Features of quartz tube/quartz glass tube:
1.High purity: 99.99%-99.999% SiO2.

2.Strong Hardness: Moh's hardness 5.3-6.5.

3.High temperature resistance: can work under 1200°C continuously,

4. Acid and Alkali resistance:except hydrofluoric acid, quartz glass does not react with any acid and base. Its stability is 30
times of the ceramic, and 150 times of stainless steel

4. Electric insulation: 10000 times of usual glass.

5. High light transmittance: 85%-95%, depends on different spectrum.

6.Excellent thermal shock stability: Small thermal expansion coefficient, 5.5×10-7/℃.
