Novel Plutonium Titanate Compounds and Solid Solutions Pu2Ti2O7‐Ln2Ti2O7: Relevance to Nuclear Waste Disposal
TL;DR: In this article, the solubility limit of the compounds SrPu2Ti4O12, Pu2Ti3O8.79, and Pu2NiTi2O7, where plutonium is in the (III) oxidation state, were identified via X-ray diffraction (XRD).

Crystal chemistry of cerium titanates, tantalates and niobates
TL;DR: In this paper, it was shown that at low temperature, ≈600°C, the crystals turn black and change to monoclinic, P2/m, a =7.5', with a corresponding change to ≈CeTaO4.50.

Structure of Compounds in the Sr1–3x/2CexTiO3 Homologous Series
TL;DR: In this article, the structure of these compounds was analyzed by X-ray, electron, and neutron diffraction, showing evidence of a noncubic supercell caused by antiphase tilting of oxygen octahedra.

Pyrochlore-type compounds containing double oxides of trivalent and tetravalent ions
TL;DR: In this article, the A20 3:2B02-type double oxides were analyzed by X-ray diffract ion analyses. But the results of the analysis were limited to the cubic system with a face-centered cell similar to that found for the mineral pyrochlore.

The System La2O3— TiO5; Phase Equilibria and Electrical Properties
Abstract: Phase relations at liquidus temperatures in the system La2O3-TiO2 were studied in air. The existence of two previously unreported compounds, La2O3. TiO2 and 2La2O3-TiO2, is postulated on the basis of X-ray and microscopic examination of crystalline samples, and in the case of La2O3.-TiO2, on a maximum in the liquidus curve at that composition. Quenched liquids of the primary-phase field of rutile were found to be semiconducting. This property was related to oxygen loss from both liquid and crystalline phases and is discussed in the light of weight loss experiments, microscopic examination of quenched samples, and information obtained from the literature. Dielectric constant and loss factor of the compounds La2O3-TiO2, La2O3-2TiO2, and 2La2O3-9TiO2 are reported at 1 Mc over the temperature range 25° to 500°C.
