1. Purity SiO2 content is more than 99.99%
2. Temperature Softening point temperature is about 1730 degrees Celsius ,1100 degrees Celsius in a long time used ,short-time
maximum use temperature is up to 1450 degrees Celsius
3. Anti-corrosion Quartz glass is acidic materials, except hydrofluoric acid and 300 degrees Celsius thermal phosphoric acid, on
any other acids were shown to be inert, is the best anti acid materials. At room temperature, alkali and salt on quartz glass
corrosion degree is minimal
