摘要

A process for the preparation of mixed oxides comprising lanthanum, strontium and manganese characterized by the general formula (La1-XSrX)YMn03 with x and y being numbers independent from each other and x means a number of from 0.01 to 0.99 and y means a number of from 0.01 to 1, wherein in a first reaction stage water is removed from an aqueous solution of salts of lanthanum, strontium and to manganese by convection drying and in a second reaction stage the resulting powder or granulate of said convection drying is sintered to form the mixed ox ides, wherein the weight ratio of the salts in the aqueous solution is selected in a way to form in the mixed oxides a ratio of elements of La : Sr = (1-x) : x and (La1-XSrX) : Mn = y : 1.
