柠檬酸溶胶—凝胶法制备Ca2Co2O5粉体及结构表征
Preparation and characterization of Ca2Co2O5 powders by the citrate sol-gel method
摘要
Abstract
Ca2Co2O5 powders were prepared by the sol-gel method using calcium and cobalt nitrates as raw materials, ultrapure water as solvent and citric acid as complexing agent. The optimal process conditions were determined, and the thermal decomposition mechanism of the precursor, the phase and morphology of the Ca2Co2O5 powders were characterized by TG-DSC, XRD, FT-IR, SEM, and EDX. The results show that Ca2Co2O5 powders can be prepared by calcining the xerogel at 700 ℃ for 36 h. Prepared loose powders are sheet-like structure with an average size of 15-20 urn.关键词
