Synthesis of nanocrystalline Cd–Zn ferrite by ball …
High energy ball milling of stoichiometric (0.5:0.5:1 mole fraction) mixture of CdO, ZnO and α-Fe 2 O 3 powders in air at room temperature results in formation of a non-stoichiometric Zn-rich (Zn,Cd)Fe 2 O 4 phase with normal spinel structure having tetrahedral vacancies. The ferrite phase is initiated at 1 h of milling and after 25 h milling, 0.96 mole fraction of ferrite is formed and 0.04 ...
