Transitional Mechanism of Particle Sr3Ti2O7 Morphology in the Molten Salt Synthesis

Molten salt synthesis (MSS) is one of the simplest methods to control the morphology and size of ceramics particle. In this study, Sr3Ti2O7 particles have been synthesized using KCl, NaCl and their mixed molten salts to investigate the transitional mechanism of Sr3Ti2O7 particle morphology. Sr3Ti2O7...

Description
Summary:Molten salt synthesis (MSS) is one of the simplest methods to control the morphology and size of ceramics particle. In this study, Sr3Ti2O7 particles have been synthesized using KCl, NaCl and their mixed molten salts to investigate the transitional mechanism of Sr3Ti2O7 particle morphology. Sr3Ti2O7 particle synthesized in NaCl molten salt was larger in size and the degree of plate-like shape was also enhanced, compared with KCl molten salt. The growth kinetics of Sr3Ti2O7 particle was also investigated by thermo gravimetric (TG) analysis. The mechanism of particle growth was discussed by the observed sequential transition from interfacial reaction-controlled to diffusion-controlled mechanisms during MSS process. [PUBLICATION ABSTRACT]
