The fundamental principle of hydration polishing can be summarized as follows: during the process of ceramic polishing machining, the polishing disc and the sapphire surface undergo friction, resulting in the generation of high temperatures and pressures at the point of contact. These conditions serve to activate the atoms of the sapphire surface through the...

Nevertheless, the light coloration of the sapphire window does not have a significant impact on its optical performance. Sapphire still exhibits excellent light transmission and optical properties, and is capable of transmitting light in the visible and near-infrared wavelength ranges.

Sapphire glass, following a double-sided polishing treatment, exhibits optical properties as well as various other physical and chemical properties, thus rendering it applicable in a variety of contexts. These include scientific research, industrial production, and the daily life of electronic products. These applications underscore the distinctive attributes of this material and its considerable potential.

In the domain of precision machining, sapphire glass finds application in the fabrication of components exhibiting high precision, including bearings and sealing rings. The high hardness and wear resistance of sapphire glass enable these components to function reliably under conditions involving high loads and severe environments.  

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...
