摘要: Abstract Pure K0.5Na0.5NbO3 powders were prepared at low temperatures by an efficient method using Na2CO3, K2CO3 and Nb2O5 as raw materials urea fuel. The phase evolution of the was investigated X-ray diffractometer (XRD) thermo gravimetric analysis-differential scanning calorimeter (TG–DSC). composition morphology characterized electron probe microanalysis (EPMA) microscope (SEM), respectively. results reveal that single-phase powder can be obtained 550 °C method. as-prepared is stoichimetric, fine well-developed.
