一引言作为红外传感器窗口材料,除具有一般条件下的红外光学特性外,还应具有高熔点、高强度、高硬度,在高温、低温及辐射作用下其透过率等各种光学及物理、化学性质有良好的稳定性。为了满足这些要求,人们不断寻找具有较好的热学、力学特性和波长在5μm以上的新红外材料。象硅铝红柱石(Silia mullite)、锗铝红柱石(Germanate mullite)、氮化铝、氧化锆和锌-铝-锗玻璃陶瓷材料很快被列为将来红外传感器窗口材料的考虑对象。其中最有现实意义的是立方氧化锆单晶了。它的红外应用波段是3～5μm,同时,它那坚实耐用的特性是其它材料所不及的。
An introduction As an infrared sensor window material, in addition to the general conditions of the infrared optical properties, but also should have a high melting point, high strength, high hardness, high temperature, low temperature and radiation under the transmittance of a variety of optical and physical, Chemical properties have good stability. In order to meet these requirements, people are constantly searching for new infrared materials with good thermal and mechanical properties and a wavelength of more than 5 μm. Silia mullite, Germanate mullite, aluminum nitride, zirconium oxide and zinc-aluminum-germanium glass-ceramic materials are quickly being considered as future infrared sensor window materials. One of the most realistic is the cubic zirconia single crystal. Its infrared band is 3 ~ 5μm, at the same time, its solid and durable features that other materials can not.
