5 Inch Dia 125mm Sapphire Substrate 9.0 High Hardness 99.999％ Al2O3 Material
Single crystal sapphire Al2O3 possesses a unique combination of excellent optical, physical and chemical properties. The hardest of the oxide crystals, sapphire Al2O3 retains its high strength at high temperatures, has good thermal properties and excellent transparency. Sapphire Al2O3 optics is chemically resistant to many acids and alkalis at temperatures up to 1000 degrees C as well as to HF below 300 degrees C. These properties encourage its wide use of Sapphire Al2O3 optics in hostile environments where optical transmission in the range from the visible to the near infrared is required.
