The Four Characteristics of Sapphire Glass

High temperature resistance up to 2050°C
Sapphire glass can reach a melting point of 2050°C, which makes it an ideal material for high temperature applications. In addition, sapphire glass has a low coefficient of thermal expansion, which means that it does not expand or shrink significantly during temperature changes, maintaining dimensional stability and further enhancing its high temperature resistance.

Good corrosion resistance and chemical stability
Sapphire glass is a chemically inert material that has strong resistance to acid and alkali, so it has good corrosion resistance. In addition, sapphire glass does not react with acid and base under normal conditions, so it will not be corroded. These properties make sapphire glass chemically stable and able to maintain its performance and appearance in a variety of corrosive environments.

High hardness and pressure resistance
Sapphire glass, with a composition similar to corundum and hardness of Mohs 9, can be added through a variety of chemical elements to generate various colors, and among which colorless is mostly used. It has the advantage of higher hardness than ordinary glass, and is mainly used in the production of high-grade watch lens, high pressure resistant and wear-resistant lens, and deep-sea diving equipment windows, though the price is relatively high.

Excellent infrared optical material
It has better light transmission in the wavelength of 185nm~ 5000 nm. It is often used in the production of optical componentsand infrared optical windows, and is also widely used in infrared and far-infrared military equipment.
