Hexagonal Crystal System Sapphire Watch Case for Stable Chemical Properties

The sapphire crystal is not a glass but rather a synthetic material known for its exceptional resistance to wear, transparency, and high-temperature tolerance, making it an ideal choice for crafting luxury watches. Composed of pure aluminum oxide, it undergoes a process of melting and crystallization at elevated temperatures to form a single crystal structure due to its remarkable hardness and durability. This is why sapphire glass stands as one of the crucial components in watch casings.

Material: Synthetic sapphire are real sapphires grown in labs. They are created by duplicating the environmental conditions that naturally mined stones are formed within. Lab-created sapphires are chemically identical to mined sapphires, but they are produced in a laboratory setting. Synthetic sapphires are the hardest of all known oxide crystals, second only to diamond in hardness.

FATURES

1. High mechanical strength: the permeable infrared window material should have sufficient strength to withstand the high-speed movement of the speed pressure load;

2. Good thermal stability: the permeable infrared window material should be able to withstand the temperature shock caused by pneumatic heating and height changes, transmission ratio and refractive index should not change significantly with the change of temperature;

3. Good chemical stability: through infrared window material exposed to air, should be able to prevent the atmospheric salt solution or corrosion gas corrosion, and not easy to moisture;

4. High optical transmission rate, must be able to effectively transmit ultraviolet to medium infrared radiation;

5. Good optical characteristics, small optical scattering and good uniformity of refractive index;
Meets large window requirements.
