What is the main features and applications of Sapphire Glass?
1. Wear-resistant, high hardness, corrosion resistance, small friction coefficient, is an ideal material for precision instrument mechanical bearings;
2. Abrasion resistance, high hardness, corrosion resistance, and excellent light transmission performance, so it is also the preferred cover material for advanced watches;
3. High strength, corrosion resistance, high thermal conductivity, high thermal conductivity, high light transmission characteristics and wide light transmission band (from near ultraviolet to 7um mid-infrared band), is an ideal window material and optical component material;
4. Excellent electrical insulation performance, hexagonal symmetrical structure, stable chemical performance, excellent semiconductor and superconducting substrate materials (small leakage capacitance and parasitic capacitance);
5. The lattice constant mismatch rate between the sapphire C-plane and the III-Ⅴ and II-Ⅵ group deposited films is small (the mismatch rate with GaN is less than 4%), so it is currently the most important GaN blue LED and LD Epitaxial substrate material.
