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.
