| Abstract: | A region of selected SrO-LnO1.5-TiO2 (Ln = La, Ce, Pr, or Nd) systems was studied experimentally using X-ray diffractometry (XRD). A series of solid solutions with composition Sr4 x Ln2 x/ 3Ti4O12 having tetragonally distorted per-ovskite structures was found to exist along the tie line connecting SrTiO3 and Ln2Ti3O9. Reactions of SrLn2Ti4O12, representative compounds of the series, with SrO were also studied. Additionally, the solubility of TiO2 in Ln2O3-(3TiO2- m (Ln = La, Pr, or Nd) at 1300°C was investigated using XRD. |
