2. About sapphire glass
Single crystal sapphire possesses a unique combination of excellent
optical, physical and chemical properties. The hardest of the oxide
crystals, sapphire retains its high strength at high temperatures,
has good thermal properties and excellent transparency. It is
chemically resistant to common acids and alkali at temperatures up
to 1000 °C as well as to HF below 300 °C . These properties
encourage its wide use in hostile environments where optical
transmission in the range from the vacuum ultraviolet to the near
infrared is required. Sapphire is anisotropic hexagonal crystal.
Its properties depend on crystallographic direction (relative to
the optical C-axis).
