Product Description
Products Description
BAO RAN High purity quartz glass tube features:
1. High Temperature Resistance: Glass can work under 1200°C continuously, and in short time can even work under 1450°C. Its softening point is 1650°C, and the melting point is 1650-1800°C.
2. Corrosion Resistant: Except hydrofluoric acid, quartz tube does not react with any acid and base. The chemical stability is 30 times that of ceramic, and 150 times that of stainless steel.
3. Thermal Stability: Excellent thermal shock stability.
4. High Optical Transmission: High transmission to 85%.
5. Electrical Insulation: Electric insulation properties are 10,000 times that of usual glass.
