Sapphire is a multifunctional material that has a wide range of applications in various fields due to its excellent properties such as hardness, transparency, and chemical resistance. The following are some specific applications of sapphire glass:
1. LED manufacturing substrate: used as a substrate for high-quality gallium nitride (GaN) crystals, which is crucial for producing high brightness LEDs.
2. Vacuum/High Temperature/Pressure Chamber Window: Provides a transparent and durable window for observing the interior of vacuum chambers, high-temperature furnaces, and high-pressure equipment.
3. Watch Lens/Barcode Reader Window: Made of scratch resistant and durable material for watch lenses and barcode reader windows.
4. Protective screens for mobile phones, smartphones, and smartwatches: Sapphire glass is used as a protective screen for electronic device screens due to its scratch resistance.
5. Polarized window/xenon lamp window for LCD projectors: with specific optical properties, used for LCD projectors and xenon lamp windows.
6. Infrared optical components: Due to the excellent transparency of sapphire components in the infrared spectral range, they can be used in infrared optical devices such as lenses and windows.
7. Thermocouple protection/NMR tube: Used to protect thermocouples and as a NMR tube in scientific research.
8. Plasma etching tubes in the semiconductor industry: used for plasma etching processes in the semiconductor industry.
9. High Performance Liquid Chromatography (HPLC) Pistons/Thermometric Guides: Used for HPLC pistons and Thermometric Guides.
10. Metering and filling pumps used in the pharmaceutical, cosmetics, and food industries: Due to their chemical compatibility and wear resistance, they are used as materials for metering and filling pumps.
11. Medical implants/endoscopic lenses: Sapphire is used as an implant and endoscopic lens in medical applications due to its biocompatibility and optical properties.
These applications highlight the diverse and critical role that sapphire glass plays in various fields from electronics and optics to medical and scientific fields, and its unique combination of properties makes it a valuable material suitable for demanding professional applications.
