Exceptional Material Properties of Sapphire Wafers
Sapphire (Al2O3), a single crystal form of aluminum oxide, stands out in high-tech applications. It offers several outstanding properties, such as:
High hardness: Sapphire ranks as the second hardest material after diamond. This quality makes the wafers highly resistant to wear and tear.
Thermal conductivity: Sapphire efficiently dissipates heat, which is critical for high-power devices like LEDs and lasers.
Optical transparency: Sapphire allows transmission of UV, visible, and infrared light, making it ideal for optical sensors and displays.
Electrical insulation: Sapphire’s very low electrical conductivity makes it perfect for electronic and photonic applications requiring electrical isolation.
These superior properties guarantee that sapphire wafers perform better than many other materials in demanding applications.
