Description:

Sapphire is one of the hardest materials in the world, sapphire Mohs hardness is 9, manufacturing a sapphire case the whole process is very complex, high technology, production cycle is very long. SAPPHIRE CRYSTAL generally refers to synthetic sapphire, and people's usual understanding of jewelry - natural sapphire has a great difference, generally used in the manufacture of watch mirror, anti-fall anti-scratch mobile phone cover plate, high requirements to protect the observation window, in recent years, the cost of synthesis is reduced, the application market is increasing. Gradually in photography, beauty instruments, instrument protection window applications. For watch lovers, watch sapphire mirror is a common and very popular mirror material. Sapphire has the characteristics of bright color, high hardness, wear resistance, etc., so it is widely used in watch manufacturing. But at the same time, because of the prevalence of high counterfeiting, it is particularly important to identify the authenticity of the watch sapphire mirror.

Identification:

1. Look at color

Watch sapphire mirror should show a certain degree of transparency, and with a deep blue or purple halo, if the mirror shows more white or other color halo, it may be fake mirror. In addition, it should also be observed from both sides, if the color is obviously asymmetrical, it may also be a fake mirror.

2. Feel observation

Watch sapphire mirror surface should be relatively smooth, no bumps or depressions occur. If it feels granular when touched, or the surface is too smooth, it may be a fake sapphire mirror. Therefore, we need to carefully observe the surface texture, and gently touch the surface with our hands to feel whether the feel is really smooth as sapphire.

3. Determine the weight

When judging the watch sapphire mirror is true or false, you can try to put the watch on a sapphire of the same size to compare the weight. The real sapphire stone weight is heavier, and the touch is cold, if the watch sapphire mirror is lighter than the sapphire stone, or the touch is not cold, it is very likely to be a false material mirror.

Applications:

Sapphire is composed of alumina (Al2O3), which is composed of three oxygen atoms and two aluminum atoms in covalent bond type, its crystal structure is hexagonal lattice structure, which can work under harsh conditions close to 2000℃ high temperature, so it is widely used in infrared military devices, high-intensity laser lens materials and light mask materials; Its unique lattice structure, excellent mechanical properties, good thermal properties make sapphire crystal often used as a photoelectric component material, sapphire glass/ruby glass has very good thermal characteristics, excellent electrical and dielectric properties, and chemical corrosion resistance, it is high temperature resistance, good thermal conductivity, high hardness, infrared penetration, good chemical stability. Therefore, it is commonly used to replace other optical materials to make optical components, infrared optical Windows, and is widely used in infrared and far-infrared military equipment, such as: It is used in night vision infrared and far infrared scopes, night vision cameras and other instruments and satellites, space technology instruments and instruments, as well as Windows for high-power lasers, various optical prisms, optical Windows, UV and IR Windows and lenses, observation ports for low-temperature experiments, and has been fully used in high-precision instruments and meters for navigation, aerospace and aviation. Sapphire is a single crystal of aluminum oxide, which is only as hard as diamond in nature. With a Mohs hardness of 9 and good biocompatibility, it can be processed into almost any shape to meet the needs of applications.
