Sapphire Crystal Window Sapphire windows are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; high-durability windows and movement bearings;Due to sapphire's remarkable hardness (third hardest mineral, right behind diamond and moissanite). Features of Sapphire Crystal 1. High-hardness - abrasion resistance 2. Transparency - in the range from ultraviolet to infrared light (0.15 - 5.5 �µm) 3. Chemical resistance and heat resistance - resist almost all kinds of acid and alkaline, heat up to 2000 �ºC. 4. Suitable for the application of insulation property required.
