(1-x) PbTiO_3-xMg TiO_3 metastable solid solutions with x up to 0.5 were prepared by heating alkoxy-derived gels at 773K for 24 h. X-ray diffraction analysis reveals that the perovskite solid solutions were obtained as a tetragonal structure when x < 0.2, and as a cubic structure when 0.2 < x < 0.5. Dielectric measurements for the pressed powders show that no dielectric peak due to a ferroelectric phase transition was observed for the solid solutions. Both dielectric constants and dielectric losses decreased with increasing Mg content.
