Abstract

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.
