摘要/Abstract

摘要： 以硝酸铁和硝酸钴为原料, 柠檬酸为络合剂, 采用溶胶–凝胶法合成具有高红外辐射性能的钴铁氧体, 并考察初始混合溶液pH (pH=1、3、5、7)对CoFe₂O₄红外辐射性能的影响。利用FTIR、TG/DSC、XRD、SEM、BET和红外发射率测试等对CoFe₂O₄的形成过程、结构、形貌以及红外辐射性能进行表征。结果表明: 不同pH的初始混合溶液所得干凝胶均具有自蔓延燃烧特性, 经600℃煅烧后得到无杂质的尖晶石型CoFe₂O₄粉体。研究发现, 初始混合溶液的最佳pH为5, 此时样品8~14 μm波段的红外发射率最高(0.92), 形成以介孔为主的孔结构, 比表面积为65.44 m²/g。

Abstract: Cobalt ferrite powders with excellent infrared radiation property were synthesized via the Sol-Gel method, where iron nitrate and cobalt nitrate were used as the original materials and citric acid as the chelating reagent. The effects of pH of the starting solution (pH=1, 3, 5 and 7) on the infrared radiation property of CoFe₂O₄ powders were examined according to the normal direction emissivity. The structure and morphology of the powders were characterized basing on FTIR, TG/DSC, XRD, SEM and BET measurements. It was found that the dried gels obtained from the starting solutions possessed the self-propagating combustion behavior. The pure spinel CoFe₂O₄ powders were obtained by the further treatment of sintered at 600℃ for 2 h. It was foumd that the optimum pH of the starting solution was 5. Under this condition, the highest infrared emissivity (0.92) of the sample was achieved in the 8-14 μm waveband, and the primary mesoporous structure was formed with the largest specific surface area of 65.44 m²/g.
