Saint-Gobain’s synthetic sapphire is the material of choice for a variety of applications ranging from optical windows for military sensor systems to tubes, rods, and viewports for industrial and semiconductor markets, Its unique properties make it a cost-effective solution where high performance and long life are critical, including extreme conditions such as high-temperature, high-pressure or harsh chemical and physical environments.
One of the hardest materials in existence, sapphire is virtually scratch proof which helps it maintain its integrity in demanding physical environments. It has a melting point of over 2000 °C, making it ideal for high-temperature applications. It is chemically inert and easily withstands harsh chemicals such as fluorine plasma and other industrial gasses and fluids, with no particle generation. In addition, sapphire can transmit ultraviolet, visible and infrared light was well as microwaves, a range broader than most materials.
