These excellent optical, mechanical, thermal, chemical and electrical properties determine its important position and role in the military and civilian fields.

(1) Chemical stability: Sapphire has a high degree of chemical stability and will not be corroded during most chemical reactions.

(2) Mechanical properties: Due to its high hardness and high strength, sapphire single crystal can maintain high strength, wear resistance and high stability in different environments ranging from ultra-low temperature to 1500 ℃ high temperature. At the same time, it is the oxide crystal material with the highest hardness currently known, second only to diamond up to 9 on the Mohs scale.

(3) Optical transmittance: The penetration wavelength range of sapphire single crystal material is 0.19nm-5.5nm, coupled with its excellent chemical stability, abrasion resistance, high hardness and high temperature resistance, make the windows made of sapphire and Sensor optical parts are widely used in high vacuum systems, high temperature furnaces and other harsh environments.

(4) Thermodynamic properties: The melting point of about 2050°C, coupled with superior chemical, mechanical and optical properties, make sapphire crystals widely used in many harsh processing environments.

(5) Wear resistance: Because of its high hardness and transparency, sapphire crystals are often used to make wear-resistant windows or other precision mechanical parts.

(6) Dielectric properties: dielectric insulation and constant dielectric constant.

(7) Sapphire also has high tensile strength, erosion resistance, thermal conductivity, and remarkable thermal shock resistance.
