Abstract

ZnAl2O4 spinel was prepared by both the sol‐gel method and by the solid‐state reaction technique. Physical properties of the product obtained by the two methods are compared. Sol‐gel‐derived ZnAl2O4 showed evidence of crystals at as low as 264°C. Quantitative X‐ray diffraction (XRD) methods utilizing the adiabatic principles of XRD analysis of mixtures were used to study the formation of ZnAl2O4 quantitatively. Data obtained in this investigation support the model that the diffusing species in the formation of ZnAl2O4 is a one‐way transfer of ZnO to Al2O3 particles as opposed to an interdiffusion of both ZnO and Al2O3. 1988 The American Ceramic Society
