Abstract
A series of solid solution xTiFe2O4.·(1-x) Fe3O4 was synthesized by ceramic method over a whole range of the composition, 1≥x≥0. Changes of the Curie point, saturation moment and the lattice parameter with the composition were examined. Generalized titanomagnetite having some vacant site in the structure normally occupied in a spinel was also prepared by oxidizing the TiFe2O4-Fe3O4 solid solution series. The region within which the spinel structure can be in existence as a single phase was settled in a FeO-Fe2O3-TiO2 system. An equal lattice parameter line, equal Curie point line and equal saturation moment line for the generalized titanomagnetite were drawn on the FeO-Fe2O3-TiO2 system.
