plate for vacuum equipment watch window Welcome to Know Sapphire~~Sapphire without impurities is a transparent crystal with no
absorption from the visible spectrum to the infrared (5μm) range. A
window made of this sapphire. Sapphire crystal can be used as
protective glass because its hardness is very high and it is not
easy to be damaged.
Synthetic sapphire is a 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 a 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 the 1990s for LED, the demand for 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
