摘要
以ＬＢＣＦ（Ｌａ０．６Ｂａ０．４Ｃｏ０．２Ｆｅ０．８Ｏ３）为模型报道了络合树脂法合成多取代复合氧化物，并通过ＴＧ、ＦＴ—ＩＲ、ＸＲＤ、比表面测定技术考察了制备过程及所得粉体的性质。结果表明，制备过程中前驱体经自催化燃烧形成Ｍ—Ｏ键，进一步在８５０℃下煅烧，可以得到纯相钙钛矿复合氧化物。该法所得粉体粒径小，具有较大的比表面积。
omplex resin route to prepare multiple-substituted mixed oxides is reported
using LBCF(La0.6Ba0.4Co0.2Fe0.8O3) as a model.TG,FT-IR,XRD,specific surface area
measurement are applied to investigate the preparation process and the properties of the oxide
powder produced.It shows that M-O bond is formed during autocatalysis combustion of the
precursor,pure perovskite oxides can be acquired after further calcination at 850 .The resulting
powder has small particle size and large specific surface area.
