The Systems ZnO‐Fe2O3‐SnO2 and MgO‐Fe2O3‐SnO2 at 1060°C

Abstract
Zn2SnO4, an inverse spinel, and ZnFe2O4, a normal spinel, form a complete series of solid solutions in the system ZnO‐Fe2O33nO2. The variation of cell dimensions with composition varies from 0.8439 nm (ZnS2nO4) to 0.8660 nm (ZnS2nO4) and exhibits a positive deviation from a linear relationship. Mg2SnO4 and MgFe2O4, both predominantly inverse in nature, have only an incomplete series.
