Lead-free SrBi4Ti4O15 and Bi4Ti3O12 material fabrication using the microwave-assisted molten salt synthesis method

In this paper, the microwave-assisted molten salt method (MAMSS) and molten salt method (MSS) were used to synthesize SrBi4Ti4O15 (SBT). The phase constitution was determined by powder X-ray diffraction and the microstructure of powder was examined by scanning electron microscopy. In contrast to the conventional MSS method, MAMSS produces more distinct plate-like grains and synthesizes both SBT and Bi4Ti3O12 (BTO) at 600 degrees C with a 30-min soaking time. The increase of temperature and soaking time can make the plate-like grains of BTO more distinct.
