Sapphire glass is composed primarily of alumina, exhibiting high hardness, excellent light transmission, superior thermal stability, remarkable impact resistance, and remarkable chemical stability. These properties render sapphire glass an optimal material for numerous high-tech applications.

Sapphire boasts a wide range of applications, including use as a practical substrate material for semiconductor diodes, as well as ideal materials for high-power laser windows and laser matrix.

In this process, the sapphire glass was placed in a high-temperature annealing furnace, where it was heated according to a predefined temperature profile to 1750-1800℃, maintained at this temperature for approximately 40 hours, and then cooled to room temperature. This approach not only significantly shortened the annealing cycle but also reduced processing time and...

Sapphire windows demonstrate high transmittance in ultraviolet, infrared and visible wavelengths, thus meeting the requirements of multi-mode composite guidance. Additionally, the sapphire light filter exhibits exceptional mechanical properties, chemical stability, and high temperature resistance. It displays excellent performance, including high strength and hardness, which also renders it well-suited for utilization as a wave-transmitting plate.

Sapphire windows boast high transparency and transmittance characteristics, rendering them highly applicable in scientific, technological and industrial contexts.
