Information of Sapphire |
| |
Sapphire, chemically known as Aluminum Oxide (Al2O3), naturally occurs as a white powdery material. Renowned for its hardness, sapphire ranks a 9 on the Mohs scale, making it one of the toughest minerals. |
| |
This material boasts wide band transmission capabilities, spanning from UV to Mid-IR wavelengths (0.15-5.5m). Its outstanding properties include high hardness, exceptional strength, scratch resistance, high temperature tolerance, chemical inertness, and superior radiation stability. |
| |
These unique attributes position sapphire as the ideal choice for optical components such as windows, tubes, rods, and balls, widely employed in scientific, industrial, and military applications. Its reliability and performance under diverse and demanding conditions underscore its critical role in these fields. |
