Ferroic materials play a key role in a wide range of technologically relevant devices. They all share the common feature that the microstructure and domains determine to a great extent their functionality. Among the promising piezoelectric materials for actuation applications is the solid solution Bi0.5Na0.5TiO3 (BNT)-SrTiO3 (ST). Recently it was found that this material is characterized by a core-shell microstructure that largely determines its electromechanical and dielectric properties [1]. In this contribution, we reveal the core-shell and domain formation in nanoparticles during a calcination process by means of in-situ TEM experiments. The solid state chemical reactions occurring upon heating could be followed in real time and the temperature-dependent core-shell formation and structural evolution was investigated. The experiments were carried out varying from 300 °C up to 800 °C using a dedicated in-situ TEM holder and a MEMS heating chip. Domain nucleation processes in the nanoparticles were observed. A domain-like structure was observed at T = 800 °C and atomic resolution was possible due to the high thermal stability and low-drift conditions. In situ TEM calcination temperature ramps were established according to previously obtained thermo-gravimetric analysis (TG/DTA) and ex-situ X-ray diffraction (XRD) results [2]. Ferroelectricity of core and shell was confirmed via PFM [3].
