AN investigation of the barium oxide–tantalum pentoxide phase diagram revealed the existence of several phases, Ba0.44TaO2.94, a hexagonal phase1, Ba0.5TaO3 with the tetragonal tungsten-bronze structure2, Ba5Ta4O15 with a novel hexagonal structure3 and Ba(Ba0.5Ta0.5)O2.75 with an ordered cubic perovskite structure4,5. The stability of one of these compounds… CONTINUE READING
