应用ＴＧ、ＤＴＡ、ＩＲ、ＸＲＤ和ＣＯ２－ＴＰＤ等技术对用。ｃｅｌｌｕｌｏｓｅ吸附法合成Ｌａ０．８Ｓｒ０．２ＣｏＯ3（ＬＳＣＯ）粉体的过程机理进行了研究．发现在制备过程中ｃｅｌｌｕｌｏｓｅ首先起着一种金属离子吸附剂的作用．在焙烧的前期阶段，ｃｅｌｌｕｌｏｓｅ先被部分氧化而在其骨架上出现了羧酸基团，并与金属离子发生螫合形成螯合离子．优化条件下，在低温合成了纯相ＬＳＣＯ粉体．然而若焙烧过程中产生的ＣＯ２不能及时地排出，会导致体相中碳酸盐的形成,从而需要高于８００℃的再焙烧才能获得纯相的ＬＳＣＯ粉体．
Application of TG, DTA, IR, XRD and CO2-TPD and other technologies to use. The synthesis mechanism of La0.8Sr0.2CoO3 (LSCO) powder by cellulose adsorption was studied. Cellulose was found to act primarily as a metal ion sorbent during preparation. In the early stages of calcination, cellulose is partially oxidized to give rise to carboxylic acid groups on its backbone and to complex with metal ions to form chelating ions. Under optimized conditions, pure phase LSCO powder was synthesized at low temperature. However, if the CO2 generated during the calcination can not be discharged in time, it will lead to the formation of carbonate in the bulk phase, requiring more than 800 ° C for re-roasting to obtain a pure phase of LSCO powder.
