Research Progress of Transparent Ceramics for Infrared Windows and Domes
Infrared (IR) windows and domes are the key components of opto-electronic system in aircraft. The acceleration along with various harsh
extreme working environment of aircraft puts higher demands on the optical
thermal and mechanical properties of IR transparent materials. Transparent ceramics which can be applied in IR windows and domes include oxide transparent ceramics (Al

thermal and mechanical properties of the above ceramics were compare
d; physical and chemical properties of these ceramics were introduced in this paper. The study mainly reviews the research progress of different ceramics from powders
ceramic forming and sintering
and compares the current research and application gaps at home and abroad. To realize the application of transparent ceramics in the fields of IR windows and domes
it is necessary to increase investment in synthesizing high-performance powders
improving ceramic density
reducing grain size
enhancing mechanical and optical properties
and preparing high-quality products with large size and complex shape. Finally
the application and development prospects of various transparent ceramics were compared mainly from the aspects of optical and mechanical properties.
