Research on Preparation and Structure of Ca3Co4O9

摘要：

　　Ca3Co4O9 particles were synthesized using cobalt nitrate,calcium nitrate,and citric acid as the starting precursors by sol-gel method.The absolute ethyl alcohol was selected as the solvent.LFA447 was applied to measure the thermal conductivity from room temperature to 300℃ as the reference to decide the optimal parameters.And the optimal parameters obtained are as follows: ethyl alcohol 100ml,ethylene glycol 5ml,citric acid 12.11g (the mole ratio of citric acid to metal ions is 1.1∶1),and pH=3 to prepare samples with total weight of 5 g.
