摘要
Abstract
Infrared windows are critical components for supersonic aircraft optoelectronics systems,demanding exceptional infrared transmittance,thermal stability,and mechanical strength in extreme environments.Calcium lanthanum sulfide(CaLa2S4)transparent ceramics have emerged as a leading candidate beyond conventional materials such as oxide ceramics,fluorides,ZnS/ZnSe,due to their broad-band transmission(8～12 μm),excellent rain erosion resistance,and mechanical robustness.This paper first elaborates on the origins of the excellent properties of CaLa2S4 ceramics,then focuses on reviewing the research progress in powder synthesis,sintering processes,and composition design of CaLa2S4 infrared transparent ceramics worldwide.It specifically analyzes the effects of fabrication processes including hot pressing(HP)sintering,spark plasma sintering(SPS),and hot isostatic pressing(HIP)sintering on the optical and mechanical properties of CaLa2S4 infrared transparent ceramics.In addition,the sulfur loss issue during the sintering of CaLa2S4 ceramics is thoroughly discussed.However,challenges remain in China regarding near-net shaping of large components,controlling sulfur volatilization at high temperatures,and understanding defect dynamics.Future research must prioritize scalable production of high-transparency CaLa2S4,synergistic optimization of thermal-mechanical-optical properties,and validation under extreme conditions to enable their engineering application in supersonic flight.关键词
