The name sapphire high-strength glass itself contains many fascinating characteristics and a wide range of application scenarios. It is not a gemstone directly obtained from nature, but a single crystal material formed by high-tech means, mainly composed of aluminum oxide (Al ? O ∝), which crystallizes at high temperatures. This material has demonstrated value in multiple fields due to its physical, chemical, and optical properties.

1、 Chemical stability and corrosion resistance

One of the core advantages of sapphire high-strength glass is its chemical stability. The chemical properties of alumina are extremely stable, exhibiting excellent resistance to both acids and bases, which endows sapphire glass with high corrosion resistance. In complex and ever-changing industrial environments, this characteristic is particularly important as it can resist the erosion of various chemicals and maintain the integrity and functionality of materials. Whether it is the erosion of strong acids and alkalis, or immersion in corrosive liquids such as seawater, sapphire glass can perform well and become the preferred choice for many materials that require high corrosion resistance.

2、 High melting point and thermal stability

The high melting point of sapphire glass is about 2040 ° C, which makes it play a crucial role in high-temperature applications. In high-temperature environments, many materials can soften, deform, or even melt, while sapphire glass can maintain its original hardness and stability. In addition, its low thermal expansion coefficient ensures dimensional stability in different temperature environments, which is particularly important for applications that require precise control of size and shape. Therefore, sapphire glass has been widely used in aerospace, high-temperature furnaces, and industrial equipment that requires high-temperature resistant windows.

3、 Optical performance

The application of sapphire glass in the field of optics is also remarkable. It has excellent transparency in the ultraviolet (UV), visible light, and near-infrared (NIR) regions, as well as high refractive index (1.75 to 1.77) and low absorption coefficient. These characteristics make sapphire glass an ideal choice for applications that require high optical clarity, such as high-precision lenses, optical windows, and optical instruments that require low light loss. In addition, its high transparency and low scattering characteristics also give it unique advantages in fields such as laser technology and optical communication.

4、 Hardness and mechanical strength

The Mohs hardness of sapphire glass reaches 9, which endows it with excellent scratch resistance and can maintain surface smoothness and clarity even in harsh usage environments. At the same time, its tensile strength and bending strength are also excellent, able to resist fracture and deformation in high stress environments. These excellent mechanical properties make sapphire glass an ideal material for products that require high durability and scratch resistance, such as watch dials and smartphone screen protectors.

5、 Electrical performance and piezoelectric characteristics

As an insulating material, sapphire glass has low electrical conductivity, which gives it a unique advantage in electrical insulation applications. In high voltage and high electric field environments, stable insulation performance can be maintained to ensure the safe operation of electrical equipment. In addition, sapphire glass also has piezoelectric properties, which can generate charges in response to mechanical stress. This characteristic has been widely used in sensors, converters, and other fields. By measuring the changes in charge generated under pressure, precise measurement and control of mechanical stress can be achieved.

6、 Diversified application areas

Based on the aforementioned properties, sapphire high-strength glass has been widely used in various fields. In the watch industry, sapphire glass has become a standard feature for watch dials due to its scratch resistance and durability; In the field of optics, it is used to manufacture high-precision lenses and optical windows; In the field of consumer electronics, screen protectors for devices such as smartphones and tablets have also begun to use sapphire glass to improve durability and scratch resistance; In the aerospace field, sapphire glass is used in key areas such as missile domes and cockpit windows due to its high strength and high temperature resistance; In the field of medical devices, sapphire glass is used in the manufacturing of endoscopes, surgical instruments, and other equipment due to its biocompatibility and corrosion resistance; In addition, sapphire glass has shown great potential for applications in fields such as high-voltage sensors and semiconductor industry.

Sapphire high-strength glass has demonstrated extraordinary application value in multiple fields due to its chemical stability, high melting point, excellent optical properties, high hardness and mechanical strength, as well as unique electrical and piezoelectric properties. With the continuous advancement of technology and optimization of processes, we believe that sapphire high-strength glass will play its unique advantages in more fields and contribute more to the development of human society.
