Abstract

Wide interest has recently been manifested in the use of ceramic materials in their special application to electrical uses. Because most of the investigation into the properties of these materials, especially of the titanates and their solutions, has been conducted primarily from the electrical standpoint, it was proposed to determine by x-ray diffraction to what extent the compounds CaTiO3 and SrTiO3 go into solid solution when mixed in varying percentages, and fired at different temperatures. It was also proposed to determine to what extent such a compound of CaTiO3-SrTiO3 will go into solution with BaTiO3 under similar conditions. As a consequence, it was desired, 1. to determine the variation in lattice parameters of the resulting crystal structure of these mixtures, 2. to determine the effects of various firing temperatures on the lattice parameters, and 3. to determine a possible correlation between the lattice parameters and the known dielectric properties.
