What is sapphire?  


 Synthetic Sapphire is a single crystal form of corundum, Al2O3, also known as alpha-alumina, alumina,

and single crystal Al2O3. Sapphire is aluminium oxide in the purest form with no porosity or grain boundaries, making it theoretically dense. The combination of favourable chemical, electrical, mechanical,optical, surface, thermal, and durability properties make sapphire a preferred material

for high performance system and component designs. For various semiconductor applications,

sapphire is the best choice in comparison with other synthetic single-crystals.




Sapphire glass are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal

conductivity, high dielectric constant and resistance to common chemical acids and alkalis.

Sapphire is the second hardest crystal next to diamonds and, because of their structural strength,

sapphire windows can be made much thinner than other common dielectric windows with improved transmittance.Chemically, sapphire is single crystal aluminum oxide (Al2O3),and is useful in a

transmission range from 0.2 - 5.5µm.
