Abstract
New solid solutions with pyrochlore structure have been evidenced in the tw o binary systems Y2Ti2O7 - Fe2TiO5 et Eu2Ti2O7 - Fe2TiO5. The domain of com position of the solid solutions was defined by X-ray diffraction, 0-33 and 0-40% (Fe2TiO5), respectively, for Y2Ti2O7 et Eu2Ti2O7 The space group of t he solid solutions is Fd3m. A contraction of the cubic cell parameters is o bserved for the two solid solutions which are non-stoichiometric.
