Sapphire explained

Glass Sapphire crystal or crystalline corundum, is unlike the gemstone which he get it name from, artificially produce. French chemist Auguste Verneuil is the creator of synthetic sapphire that he produced for the first time in 1902.
The sapphire is usually produced by crystallizing aluminum oxide powder (Al2O3) at high temperature and pressure. There is different development process sapphire crystals of which the most used are the ISM (polycrystalline), KY HEM and EFG CZ (Monocrystalline).
Key Benefits of Sapphire are:
– A very good transmission in the UV – NIR
– Incredibly, tougher What Other Optical glasses (Thermal shock, chemical, mechanical)
– Highly resistant to scratches and abrasion (9 on the Mohs hardness scale, just below the diamond)
– Very high melting temperature
However its high hardness makes it hard for machining, especially complex shapes.
Its transparency and its exceptional hardness make it a coveted glass pour the following applications:
– Watches: watch glass (ONLY scratched by diamond)
– Scanner Glass: Often prone to scratches
– Windows Phone: Apple use pay Fingerprint readers, the Cameras and SOME watches.
– Windows to Resist high temperatures or pressure: laser applications
