2. Melting point: The melting point is as high as 2050 ℃, far higher than ordinary glass.

3. Transmittance: Has good transmittance, especially in the ultraviolet and infrared regions.

4. Chemical stability: Good chemical stability and strong corrosion resistance.

5. Thermal stability: It has excellent thermal stability and can withstand drastic temperature changes.

2、 Application

Due to its excellent performance, sapphire glass is widely used in the following areas:

1. In the field of optics, it is used as a window material, lens, prism, etc. in laser, infrared, ultraviolet and other fields.

2. In the field of electronics: used as insulation material, heat sink, etc. in semiconductor devices, LEDs, etc.

3. Aerospace field: As a material with high temperature resistance, wear resistance, and good transparency, it is applied to spacecraft windows, solar panels, etc.

The above are the properties and applications of sapphire glass. In today's materials science field, special glass is widely used in various high-tech fields due to its unique physical and chemical properties. Sapphire is composed of aluminum oxide and has a hexagonal lattice structure, in which three oxygen atoms and two aluminum atoms are covalently connected. It has the characteristics of high sound speed, high temperature resistance, corrosion resistance, high hardness, high transmittance, and high melting point (2045 ℃), making it a relatively difficult material to process. Therefore, it is often used as a material for optoelectronic components.
