Optimize process parameters of microwave-assisted EDTA method using orthogonal experiment for novel BaCoO3−δ perovskite

This study proposed a novelty process and an optimization study on the synthesis of the BaCoO3−δ perovskite powders using microwave-assisted EDTA method. OA16 (45) orthogonal experiments were employed to optimize the process parameters such as precursor pH, microwave time, microwave power and calcination temperature. The decreasing order RB > RA > RD > RC indicates that the level of significance of factors are as follows: microwave radiation time (6.68) > pH value of precursor solution (3.50) > calcination temperature (2.00) > microwave power (1.83).113
