摘要：

Ca3Co4O9　powders　were　synthesized　by　the　tartaric　acid　complexing　sol-gel　method　using　metal　nitrate　as　raw　materials.　The　pyrolytic　decomposition　mechanism　of　the　gel　and　formation　process　of　Ca3Co4O9　were　investigated　by　DTA-TG,　XRD,　FT-IR　and　SEM　etc.　The　results　show　that　nitrate　ions　accelerate　the　decomposition　of　the　gel,　and　the　platelike　Ca3Co4O9　powders　with　the　mean　size　of　0.6　μm　can　be　obtained　after　the　dry　gel　calcined　at　750°C　for　2　h.
