We have prepared a soluble manganese alkoxide, and used in the first all-alkoxide synthesis of Ca, Sr, and Ba substituted lanthanum manganites. The phase devlopment from gel to target oxide was monitored by TGA, DSC, powder-XRD, FT-IR spectroscopy, and TEM-EDS. Here present the effect of dopant on the phase develpment. It was found that the dopants influence the temperature of complete oxide formation (>650°C). The main difference in phase evolution was seen in the n the seemed to temporarily reduce the elemental homogeneity. 300-600°C range, where the formation of crystalline phases in trace quantities seemed to temporarily reduce the elemental homogeneity.2005-10-312005-10-31
