Synthesis of Bi0.5(Na0.7K0.2Li0.1)0.5TiO3 Powders through Molten Salt Method
The Bi0.5(Na0.7K0.2Li0.1)0.5TiO3 powder synthesis through molten salt method was investigated in the temperature range of 650 ~ 700°C for 2 ~ 4h. The XRD results indicated that the optimal synthesizing temperature for molten salt method was 700°C, significantly lower than that for conventional processing route of solid state reaction method, where a calcining temperature of 850°C was needed. The SEM results revealed better crystallization of the powders obtained through molten salt method, compared with those through the conventional processing route of solid state reaction method.
