Sapphire, which is derived from the Latin Spphins, which means blue; it belongs to the corundum group of minerals in the trigonal crystal system. In the gem world, all colors of gem-grade corundum other than rubies are called sapphires.
The main component of sapphire is alumina (Al2O3). Corundum contains trace elements such as iron (Fe) and titanium (Ti), and presents colors such as blue, sky blue, and light blue, among which the bright sky blue is the best.
Sapphire, as a segmented application component throughout the terminal, is widely used in laser, infrared, communications, semiconductors, electronics, watches, medical beauty, precision instrumentation, military, aviation, auto parts, and smartphones and many other cutting-edge high-tech fields, for customers to provide long-term large number of stable sapphire and other optical devices.
