China Large Diameter Quartz Glass Tube with High Purity

Large Diameter Quartz Glass Tube With High Purity
Quartz glass tube is a special industrial technology glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties for electric fire barrels, electric baking stoves, electric heaters, and heating.

Advantage of Quartz Tube:
1. High purity , SiO2> 99.99%.
2. Working Temperature: 1250ºC; Soften Temperature: 1730ºC .
3. Good thermal stability.
4. Acid-proof, Alkali-proof.
5. Excellent electrical insulator.

6.Transmission: Visible light >93%, UV light>85%.
