Product Description
Quartz is one of the hardest materials, which is virtually scratch-proof. It helps to maintain its integrity in demanding physical environments. It has a melting point of over 2000 °C, making it ideal for high-temperature applications. Besides, sapphire can transmit ultraviolet, visible, and infrared light as well as microwaves, a range broader than most materials.
Its unique properties make it a most suitable solution for a variety of applications ranging from optical windows for optical systems to tubes, rods, and viewports for industrial and semiconductor markets.
