Abstract
The reaction between lanthanum oxide and strontium carbonate was studied non-isothermally between 350 and 1150 °C at different heating rates, intermediates and the final solid product were characterized by X-ray diffractometry (XRD). The reaction proceeds through formation of lanthanum oxycarbonate La2O(CO3)2, lanthanum dioxycarbonate La2O2CO3, and non-stoichiometric strontium lanthanum oxide La2SrOx (x = 4 + δ). La4SrO7 was found to be the final product which begins to form at ∼700 °C. Li+ doping enhances the formation of the final product as well as commencement of the reactions at lower temperatures.
