“…In the last years, the literature has reported the formation of barium tungstate (BaWO 4 ) by different techniques, such as: solid-state reaction [1,2], Czochralski [3][4][5], high temperature flux crystallization [6], hydrothermal-electrochemical [7], polymeric precursor [8,9] and molten salt [10]. However, these methods generally need of high reaction temperatures, long reaction time and sophisticated equipments.…”
