With the advancement of science and technology, more and more synthetic materials are used in industry. The rare and expensive nature of natural gemstones has also urged synthetic technology to be used in the synthesis of gemstones.sapphire green color
The research on synthetic sapphire has a long history, and the technology is constantly improving. The difference from natural corundum can be measured by basic gemological characteristics such as microscopic characteristics, dichroism and spectrum, and large instruments such as XRF can also be used for testing.
Sapphire has a high hardness, with a Mohs hardness of 9, second only to diamond. Synthetic sapphire crystals have stable physical and chemical properties (thermal properties, electrical properties, etc.) and good light transmittance.
In addition to being used for gems, sapphire is also widely used in military and industry, such as filters, superconductor substrates, electrical insulators, sapphire lenses, etc. Synthetic sapphire is closely related to our lives.
