摘　　要：透明尖晶石陶瓷(TMAC)材料具有耐高温、耐腐蚀、较高的硬度和机械强度等优点,透过波段从紫外、可见、中波红外到微波,是性能优异的宽波段窗口材料,能够满足不断发展的光电系统对窗口材料的多重要求,且有广阔的应用前景。对采用热压烧结结合热等静压工艺制备出的TMAC材料进行了透过性能研究,分别对可见和红外波段镀制了增透膜,测试了不同入射角的红外透过率,并根据入射角的不同镀制了增透膜,测试了镀制金刚石膜后的透过率,并对毫米波波段的透过率做了初步测试和仿真,分析了不足和未来的研究方向。Transparent spinel ceramic（TMAC） with high transmittance in the ultraviolet,visible,middle infrared and microwave regions is an excellent wide band windows material,and can meet the development of photoelectric system for its thermostability,anticorrosion,and high hardress and mechanical strength,which provide broad application prospect.Researches of TMAC prepared by hot pressing（HP） and hot isostatic pressing（HIP） technology were introduced.AR-coating was used to improve the transmittance of TMAC in visible and infrared regions.The infrared transmittance with different incident angles were tested,and different AR-coating with different incident angles were coated.The transmittance in millimeter-wave band was tested and simulated.And the lacks and future research of TMAC material were also discussed in the end.
