Resumen:
A study of Sr1-xBaxHfO3 perovskites with composition x = 0, 0.12, 0.25, 0.50, 0.75, 0.88 and 1 using XR-diffraction analysis has been performed. The crystalline structures as well as the lattice constants have been determined at room temperature. The electron distribution in the unit cell of ABO3 determines the bonds between A and B cations with oxygen. Comparing cationoxygen distances with the corresponding sum of the cation plus the anion radii it is possible to infer the character of the bonds and to interpret their behavior with composition.
