Cellulose-precursor synthesis of nanocrystalline Co 0.5Cu 0.5Fe 2O 4 spinel ferrites

Nanocrystalline Cu0.5Co0.5Fe2O4powders were prepared via a metal-cellulose precursor synthetic route. Cellulose was used as a fuel and a dispersing agent. The resulting precursors were calcined in the temperature range of 450-600 °C. The phase development of the samples was determined by using Fouri...
