    摘要: PURPOSE: A preparation method of LaMO3 type composition, M being aluminium, gallium or indium, in powder or sintered form is provided, which can be used in any application requiring an oxygen conductive material in oxide form, such as fuel cells with solid oxides. CONSTITUTION: A compound in powder form is capable of reaching by loose powder sintering a density at least equal to 93 % of its theoretical density and of resulting in a sintered compound substantially free from an electrically active secondary phase at the grain boundary. The compound in powder form is obtained by reacting salts of lanthanum and of element M with a base then separating and calcining the resulting precipitate. It can also be obtained by mixing in a liquid medium salts of lanthanum and of element M and, optionally, of a base; then drying by pulverization and calcination of the resulting precipitate.
