    60mm*10mm Optical Sapphire Rod Sapphire Lens With Polishing


    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.


    Sapphire (Al2O3 monocrystalline) has a hardness (10 diamond, 9 sapphire) and high temperature (2030C) due to its single crystal structure. Sapphire's acid-base resistance and chemical corrosion, including hydrochloric acid (HF). These unique features are commonly used in most high temperature test applications:


    Transparent sapphire tubes allow real-time observation of the decomposition of geological samples at high temperatures
    Single crystal sapphire tubes are resistant to high temperatures, higher temperatures than quartz glass tubes, higher in strength and higher pressure than quartz glass tubes


    Sapphire at high temperatures is also an inert state, composed of pure Al2O3 powder, does not contain Na, K and other active metal ions, high temperatures above 1000 degrees will not be like quartz glass separated out of the gaseous conductive Na, K ions. Isotope elements do not react to sapphires. The isotopes isolated from geological samples are fully protected from contamination.
