Abstract

The activity of Fe₃O₄ in Fe₃O₄-Fe₂TiO₄ solid solutions has been experimentally determined at 800°C and 900°C at 1 atm pressure. The activity-composition relations deviate markedly from "ideal' (a = X²) behavior, requiring consideration of Fe²⁺-Fe³⁺ order on the ulvospinel-magnetite join. We have developed a solution model that takes explicit account of order-disorder and the measured activity-composition relations. The derived interaction parameters fit our activity-composition data together with other activity and cation distribution data available in the literature over the temperature range of 800-1300°C. -Authors
