Abstract
Samples of dysprosium-calcium ferrites Dy1-xCaxFeO3-y with x ranging f rom 0 to 2/3 were novelly prepared in air by solid state reaction and characterized by X-ray powder diffraction. These samples are single-ph ased orthorhombic perovskite-type compounds belonging to the space gro up D(2h)(16)Pbnm. The lattice constants of the Dy1-xCaxFeO3-v samples have been refined by Cohen's least-squares method. The initial substit ution of Ca for Dy leads to a decrease of the lattice constants. Furth er substitution of Ca for Dy has hardly any influence on the lattice d imensions. (C) 1997 Elsevier Science S.A.
