摘　　要：以球形石墨作为吸波升温载体,微波加热制备了一种具有两层包覆空腔结构的Fe-Mn-Co-Cu复合尖晶石相红外辐射材料。结果表明:当铁、锰、钴和铜的硝酸盐按照Fe、Mn、Co和Cu元素摩尔比为n Fe:nMn:nCo:nCu=6:2:1:1,微波作用加热温度为900℃,保温20 min,氧化掉包裹在内部的球形石墨后,可以得到两层包覆空心球结构的红外复合材料,在红外全波段发射率可以达到0.92。In this paper,a kind of Fe-Mn-Co-Cu spinel oxide for infrared radiation material with two layers coated cavities is prepared by microwave heating method using spherical graphite as wave assimilation and warm-up carrier.It shows that the infrared composite material with cavities coated in two layers is fabricated after oxidizing the encapsulated spherical graphite,when the molar ratio of Fe,Mn,Co and Cu nFe:nMn:nCo:nCu=6:2:1:1,the microwave heating temperature is 900°C,and the heat soaking time is 20 min.Its infrared emissivity is 0.92.
