According to customer's request |
Sapphire has high surface hardness, high thermal conductivity, high dielectric constant and resistance to chemical acids and alkalis. Since the hardness of sapphire is second only to diamond and its structural strength is very high, the thickness of sapphire windows made by enhancing light transmittance is thinner than that of general high dielectric windows.
Sapphire material is an ideal choice for applications in high pressure, vacuum or corrosive environments because it can resist strong acid corrosion, has high compressive strength and melting point, and can resist darkening due to ultraviolet radiation. Sapphire Windows are also widely used in watch covers and beauty equipment.
