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 degrees C 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.
