Information of Sapphire |
| |
Sapphire is a form of Aluminum Oxide (Al2O3). In its natural state, Al2O3 is a white powdery material. |
| |
Sapphire is one of the hardest minerials and ranks a 9 on the Mohs scale. |
| |
Sapphire offers wide band transmission from UV to Mid-IR (0.15-5.5µm). |
| |
Sapphire features exceptional properties of high hardness, high strength, scratch resistance, high temperature resistance, purity, chemical durability and superior radiation stability. |
| |
These unique properties make sapphire ideal material for optical windows, tubes, rods and balls used in many Scientific, Industrial and Military applications. |
 |
| Benefits of Sapphire |
Extremely hard, strong and wear resistant
Excellent thermal conductivity/heat resistance
Exceptionalchemical stability
Superior dielectric material with a high dielectric constant
Extremely high melting temperature (2030 °C)
Excellent transmission bandwidths (UV to IR) |
