Sapphire wafers
These are thin slices of synthetic sapphire, commonly used as a substrate in a variety of high-tech applications. Sapphire, which is a crystalline form of aluminum oxide (Al�¢??O�¢??), is valued for its hardness, optical transparency, thermal stability, and chemical resistance. Here�¢??s a brief overview of their applications and properties:

Properties of Sapphire Wafers:

Hardness: Second only to diamond, sapphire is extremely scratch-resistant.
Optical Clarity: Transparent across a wide range of wavelengths (UV to infrared), making it ideal for optical components.
Thermal Stability: Can withstand high temperatures, which is useful in semiconductor processes.
Chemical Resistance: Highly resistant to acids and alkalis, ensuring durability in harsh environments.
Electrical Insulation: Sapphire is an excellent electrical insulator.
