Bi4-xDyxTi3O12(when x = 0, 0.25, 0.5, 0.75 and 1.0) powders and ceramics were prepared by solid-state mixed oxide method. The calcination was carried out at 900°C for 4 h with heating/cooling rate 5°C/min. The ceramics were then sintered at a temperature between 950-1100°C for 4 hrs. The optimum sin...
