Q&A
Q:What is sapphire coating?
A:Sapphire coating is a thin layer of synthetic sapphire (aluminum oxide) applied to surfaces for enhanced durability, scratch resistance, and optical clarity. Known for its exceptional hardness (9 on the Mohs scale), sapphire is highly resistant to scratches and wear. It is also optically transparent across a wide range of wavelengths, making it ideal for applications requiring both clarity and durability. The coating's thermal and chemical stability further makes it suitable for use in harsh environments. Common applications include smartphone screens, camera lenses, watch crystals, high-end optics, and medical devices. Sapphire's toughness and transparency make it valuable in industries ranging from electronics and consumer products to aerospace and healthcare, where it protects surfaces and extends the lifespan of devices.
