Sapphire single crystal can be made into optical elements for experiment due to its ideal optical and mechanical properties, such as lens, prism and reflector.And the detection instruments used in scientific research, such as gravity wave detection instruments.Sapphire single crystal can be used as observation window and detection window for equipment and instruments working in various high temperature, high pressure and other harsh environments, as well as sensor and detector window for coal, gas and oil well detection due to its transmissive band, high permeability, high strength, high temperature resistance, wear resistance and corrosion resistance.
In other civil aspects, sapphire can also be used to do medical surgical tools, precision instrument shell, precision mechanical bearing and high-grade clocks and watches, jewelry.There are a variety of cup utensils, transparent lamps and lanterns and goggles, etc.
