Sapphire Components
Sapphire is a transparent single crystal alumina material with excellent chemical stability and excellent mechanical, thermal and optical properties. As a raw material, its performance is much better than glass, quartz and other mass-produced transparent materials. Jewel bearing is mainly used in instrumentation. Instrument bearing bearing load is small, but it needs high rotation accuracy, good sensitivity and long service life. The Sapphire has a small friction number, high hardness, corrosion resistance, small thermal expansion coefficient, high compressive strength, and be able to meet the requirements of the use of instrument bearings.
Sapphire can be widely used in various demanding fields with harsh requirements such as defense, scientific research and civil industry.
Main features and applications:
1. Wear-resistant, high hardness, corrosion resistance, low friction coefficient, is an ideal material for precision instrument mechanical bearings, Sapphire jewel bearing devide to hole and cup bearing, Hole Jewel bearing contains a series of components that are chiefly applied as supporting bearings to the rotational systems of various accurate chronographs, auto-memorizing apparatus, precise instruments (micrometer, dial indicator) and other apparatus.Cup jewels contain four types: spherical bearing, conical bearings, double cups on one surface bearing, and single cup on double surfaces bearing. These cup jewels are mainly used for movement system in electronic meter, hot water meter, liquid measuring instrument, single-phase KHW meter, triphase KHW meter, aviation and navigation instruments, weather apparatus and many other kinds of instruments and apparatus. ;
2. Wear-resistant, high hardness, corrosion resistance, excellent light transmission, so it is also the preferred cover material for advanced watches;
3. High strength, corrosion resistance, high thermal conductivity, high transmittance characteristics and wide light transmission band (from near UV to 7um Mid-infrared band) is an ideal window material and optical element material;
4. Excellent electrical insulation properties, symmetrical hexagonal structure, stable chemical properties, excellent semiconductor, superconducting substrate material (small drain capacitance and parasitic capacitance);
5. The mismatch rate of the lattice constant between the sapphire C-plane and III-V and II-VI deposition films is small (the mismatch rate with GaN is less than 4%). Therefore, it is currently the most important substrate material for GaN blue LED and LD. Epitaxial.
