摘要
首先用柠檬酸溶胶-凝胶（sol-gel）法制备了BaCo2Fe16O27型六角铁氧体，经不同温度焙烧后，分析产物的结构和形貌，确定出较优的焙烧温度，然后以此工艺制备W型Ba（Zn1-xCox）2Fe16O27（x=0，0．2，0．6，0．8，1．0）六角铁氧体，分析其吸波性能。研究表明，x=0．8时，样品的有效吸波带宽可拓宽到12-18GHz整个波段，吸收峰值可提高到-20dB。
Citrate sol-gel process was used to prepare BaCo2Fe16O27 hexaferrite. After roasting at different temperatures, the microstructure and morphology of the samples were analysed to determine proper roasting temperature. Then, W-type Ba（Zn1-xCox）2Fe16O27 hexaferrite was prepared by the same process, and the microwave absorbing properties was studied, The results showed that the effective bandwidth is broadened to whole range of 12-18 GHz, with a maximum absorption of -20dB at x=0.8.
