Sapphire glass can be used at temperatures up to 2000 °C. Sapphire glass is generally suitable for pressure applications; the pressure resistance increases depending on the material thickness in relation to the external diameter and free view diameter. We are happy to assist you in selecting a suitable glass. Please feel free to contact us.
