Lab Grown Synthetic Aquamarine Al2O3 Sapphire Single Crystal
Gemstone Material
Description:
Sapphire commonly known as corundum, the main component is Al2O3,
is a common simple coordination type oxide crystal. Sapphires in
nature show different colors due to the presence of some impurity
ions, such as sapphire containing titanium ions (Ti3+) and iron
ions (Fe3+) will show blue, containing chromium ions (Cr3+) will
show red, and when containing nickel ions (Ni3+), it will make the
crystal yellow. Pure alumina crystal is colorless and transparent,
because of its unique crystal structure, excellent mechanical
properties, optical properties and chemical stability, can be
applied to the high temperature environment of 2000 ° C, so it is
widely used in infrared military devices, satellite space
technology, high-intensity laser window materials and
semiconductor, large-scale integrated circuit substrate materials.
Features:
Sapphire crystal has many excellent properties, as shown in Table
1, sapphire Mohs hardness of 9, second only to diamond, high
strength, high thermal conductivity, thermal shock resistance and
chemical stability, high surface smoothness, good dielectric
properties. These properties are inseparable from the unique
crystal structure. In addition, sapphire in 3 ~ 5? The M-band has a
high optical transmittance, and its single crystal transmittance
range is very wide, covering vacuum ultraviolet, visible, near
infrared to mid-infrared and many other bands. These superior
properties make the position and role of sapphire in the military
and civilian fields increasingly obvious.

Application:
The similarities between the natural and synthetic sapphire markets
go beyond the similarities in quality range and pricing. Both
natural and synthetic sapphires can be diffused to form a variety
of effects and colors - in fact, colorless synthetic sapphires that
have been diffused can turn blue entirely. The diffusion treatment
of synthetic sapphire was first recorded in the 1950s. As with
natural sapphires, diffusion-treated synthetic materials are
cheaper than untreated samples. Manufacturers do not always publish
growth methods and treatment methods, especially for cheaper
materials. However, diffusion-treated blue synthetic sappsapphire
can be simply monitored using a container filled with refractive
index matching liquid, and the color of the treated gemstone will
gather at the facet junction and waist circumference.
Diffusion-treated blue sapphires are not as good as grown blue
sapphires because the treatment is limited to the surface and
cannot be cut again. Treated gemstones are less transparent because
a thin layer of diffused surface has very different optical
properties than most cut samples.
