Welcome to Know Sapphire~~
Synthetic sapphire is transparent single crystal 99.99% pure Al2O3 that exhibits a unique combination of physical, chemical, electrical and optical properties: high thermal conductivity, high strength and scratch resistance, hardness (9 on the Mohs scale), transparent in wide range of wavelength, chemical inertness.
High crystal perfection, low reactivity, and appropriate unit cell size make sapphire an excellent substrate in the semiconductor industry for blue light-emitting diodes (LED).
Since Nobel Laureate in Physics Shuji Nakamura used the sapphire substrate in 1990s for LED, the demand of sapphire crystal has been growing rapidly.
It drives development of new markets like general lighting, backside lighting in TV-sets, displays, consumer appliances, aerospace and defense, and other applications
Sapphire physical property
- A sapphire optical window is the ideal window material for many UV and IR applications because it can transmit so far into the UV and IR bands. With its thermal and chemical robustness, a sapphire window can be exposed to extreme plasmas and temperatures, far greater than any other material, and continue to transmit high powered UV, visible and IR for years with no degradation. These properties make it an ideal material for UV/VIS/IR sensors, IR surveillance and recon and broad band inspection equipment (especially when abradants are involved).
- Sapphire windows are the ideal material for pyrometry. They transmit a wide range of wavelengths while safely isolating hot zones up to 2000C from external room temperature observation; making sapphire windows the ideal sight window for furnaces and high temperature processing equipment.
- Medical and dental tools that require UV sterilization and curing and IR thermal processing are typical applications where sapphire windows and transparent tools excel.
