WebIn a closed packed structure of mixed oxides, the lattice is composed of mixed oxides ions. One-eighth of tetrahedral voids are occupied by divalent cations (A2+) while one half of octahedral voids are occupied by trivalent cations (B3+). The formula of mixed oxide is : Q. In a normal spinal structure, there is a closed packed array of O2− ions. WebMetal oxides play a very important role in many areas of chemistry, physical and materials science [1-6]. Metal oxides are formed as a consequence of co-ordination tendency of metal ions so that oxide ions form co-ordination sphere around metal ions and give rise to close packed structure. The different physical, magnetic, optical
