Solids 67 (2006) 1531–1536], the interrelationship between lattice constant, ionic radii and tolerance factor of cubic perovskites has been established and an empirical equation was obtained. However, the assumption of incorrect ionic coordination led to an incorrect mathematical expression even though the average relative errors between predicted and observed lattice constants of 132 materials were below 1%. Here, corrected coefficients for that empirical expression are obtained, which would likely be useful for investigation of general perovskite materials.en-USOxidesInorganic compoundsSemiconductorsEpitaxial growthCrystal growthArtigo publicado em periodicoO periódico Journal of Physics and Chemistry of Solids concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
