Product Specification

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.
