The compound La x Sr, 1‐x TiO 3 with x up to 40 at. % is observed to be homogeneous by microscopic examination. The observed X‐ray powder pattern corresponds to the cubic perovskite structure. The plot of lattice constant a 0 vs x indicates a Vegard's law dependence within the experimental error. There were no extraneous lines in the X‐ray powder pattern.
