Problem
In 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 cation ( B3+ ). The formula of mixed oxide is :
(1) A2BO3
(2) AB2O3
(3) A2BO4
(4) AB2O4
