“…However, this preparation process causes inhomogeneity, irregular morphology, large particle size, and broad particle size distribution, and it requires long heating times followed by several grinding and annealing processes [11]. Various synthesis methods have been applied to overcome these drawbacks which include the combustion process [5,25,26], the co-precipitation method [23,27,30], molten salt synthesis [20], the sol-gel method [8,22], the spray dry method [2,10,28], and spray pyrolysis synthesis [11,19,29].…”
