Correlation between mechanochemical reactivity forming ABO4-type complex oxides and the structures of product materials

Through the experiments for syntheses of ABO4 (A: Al, Fe, Cr, In, La, Bi; B: P, V, Nb, Sb), investigations on the relation between mechanochemical reactivity and (I): the crystal structure of starting materials or (II): the crystal structure of product materials has been conducted. It has been found that it is a necessary condition to use structurally active substances against milling operation for the occurrence of a mechanochemical reaction. In addition, it is easier to facilitate a mechanochemical reaction to form ABO4-type oxide which is of larger size of cation and in denser structural state.
