In the previous papers we reported on the formation and the constitution of zincferrite, and in this paper we report on the solubility of Fe2O3 and ZnO in zinc-ferrite at a high temperature that was ascertained with the Xray-and magnetic analysis.
In conclusion: The excess of Fe2O3 makes a solid solution with zinc-ferrite and this solid solution is ferro-magnetic and at above 1200°C a part of the excessive Fe2O3 decomposes to Fe3O4 and also this Fe3O4 makes a solid solution, but ZnO is slightly soluble in zinc-ferrite and this is not ferromagnetic.
