On the formation and decomposition of zinc ferrite under sintering conditions Rawling, John Roughley

Abstract

The formation of zinc ferrite from zinc and iron compounds, which reacted under sintering conditions, has been investigated. A mechanism of ferrite formation controlled by cation diffusion has been suggested and it has been shown that the nature of the reagents affects the note of ferrite formation. The decomposition of zinc ferrite by alkaline earth compounds, which reacted under sintering conditions, has also been studied. Calcium ferrite was found to be more stable than zinc ferrite but, for kinetic reasons a metastable phase of zinc ferrite was formed more readily.
