Product Description

Product Details

Sapphire crystal is an excellent multifunctional material widely used in industry, national defense, and aerospace. It has high-temperature resistance up to 2000 ℃, good thermal conductivity, high hardness (Morse 9th) and good chemical stability. Usually, this material is used for high-temperature resistant infrared window, solid laser, precision wear-resisting bearings. It is also widely applied in crystal substrate, especially for blue, purple, white light-emitting diodes (LED) and blue light laser (LD). As the hardest material among all oxide crystals, Sapphire has a combination of good optical and physical properties, which even maintains at high temperature, making it the best choice for a variety of demanding applications.
