Perovskite-type oxide (LaCoO3) fine powders were prepared by a polymer precursors (PP) methods at 300~500°C. The LaCoO3 fine powder could be prepared at 380°C when the use of EDA and PEG for organic-and polymer-additives, respectively. The surface area of LCO was ca. 39m2/g. LCO thick-film could be prepared from the steady state suspension with the addition of AcAc or PVAby the EPD method at +10V, 3min.The current density of the LaCoO3 film sensor was changed with changing HPO42- concentration at +1.00 V vs. SCE. The device showed relatively good amperometoric response to H2PO4- from 1.0x10-5M to 1.0x10-3M with the 90% response time of ca 2min. The LaCoO3-based sensor also showed a good selectivity among the examined anions of NO3-, Cl- and SCN-.
