Description

High temperature resistance, good thermal conductivity, high hardness, sapphire ingot

Product Description

Sapphire (Sapphire, molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission and good chemical stability. At the same time, it is also a widely used single crystal substrate material, and it is the substrate of choice for the current blue, violet, and white light emitting diode (LED) and blue laser (LD) industries.

Application field

In the field of optical communication, sapphire crystal is used not only as a short-wavelength active device, but also as a polarizer for passive devices;

In the field of laser, sapphire is an excellent laser dielectric material (such as Ti:Al2O3, Cr:Al2O3);

in the field of superconductivity, sapphire crystal can not only make Y-series, La-series high-temperature superconducting films, but also grow new practical MgB2 High-temperature superconducting thin films (usually single crystal substrates are chemically corroded during the production of MgB2 thin films);

An important window material widely used in high-energy detection and high-power high-power lasers.
