Phase evolution of strontium bismuth niobate ceramics by conventional solid-state reaction method

In the present study, formation of single-phase Strontium Bismuth Niobate (SBN) composition is investigated and the phase evolution is understood by studying the reaction mechanism between the raw materials and their combinations. The ceramics compositions were prepared using conventional solid-state reaction method. TG/DTA studies of all the constituents of SBN and the combination of its components have been carried out. X ray diffraction studies reveal the evolution of different phases among the raw powders thermally treated in different temperature ranges. FTIR studies reveal how different phases evolve as a function of calcination temperature. In the present study, an attempt is made to understand the effect of thermal treatment on the reaction mechanism for the formation of single-phase SBN.
