Y2O3 transparent ceramic is a widely used infrared material with excellent physical and chemical properties. Such as high melting point, high thermal conductivity, high laser damage threshold, etc. In particular, its thermal conductivity reaches to 27 W/m/K, which is about twice as high as the thermal conductivity of the currently widely used laser material YAG crystal.
Large-sized ceramics can be easily prepared using a ceramic preparation process. And large-size Y2O3 transparent ceramics can be widely used in infrared missile fairings and high-temperature infrared windows.
