Sapphire is heard in various industries, either naturally formed or artificially synthesized. Whether natural or artificially manufactured, it has strong hardness characteristics, and its main component is alumina. Sapphire is blue, butSapphire window panelIt is transparent. Why is it like this?

It is a transparent and colorless sapphire made by firing pure alumina under high temperature conditions. The high strength, hardness, and scratch resistance of the sapphire formed in this way are all improved, as the cost of processing this sapphire window plate is relatively high. Under high temperature firing, the consumption of its constituent materials is significant. Therefore, in daily life, prices will be relatively expensive. It has high hardness, comparable to strong materials such as iron and copper, and can resist external compression, prevent damage, and thus damage its internal structural components, causing losses. Secondly, it also has strong corrosion resistance and compression resistance, or in other words, it has more functions such as waterproofing, shock resistance, etc.

Sapphire single crystal is widely used as a microwave electron tube due to its excellent optical, mechanical, chemical, and electrical properties, especially its high medium wave infrared transmittance in the range of 0.190 μ m to 5.5 μ m. Dielectric materials, ultrasonic conducting elements, delay lines, waveguide laser cavities, precision instrument bearings, balance blades and other optical components, as well as window materials for infrared equipment, spacecraft and high-intensity lasers.

Sapphire window plates have a very wide optical transmission frequency band, with good transmittance from near ultraviolet (190nm) to mid infrared, making them widely used in optical components, infrared devices, high-intensity laser lens materials, and mask materials. It is a difficult to process material with characteristics such as high sound speed, high temperature resistance, corrosion resistance, high hardness, high transmittance, and high melting point (2045 ℃). As an excellent transparent material, it has good transmittance in the ultraviolet, visible light, infrared, microwave and other bands. Can meet the requirements of multi-mode composite guidance (television, infrared imaging, radar, etc.), used as window materials and fairing components, and as an important window material in the field of optoelectronic communication.
