説明

Ni/BaTiO3 core-shell particles were successfully prepared using a spray drying of a slurry precursor comprising Ni particles (100 nm) and BaTiO3 nanoparticles (20 nm) and butyl acetate. In the process, the precursor was atomized using an ultrasonic nebulizer to produce droplets, and subsequently the droplets were fed into a tubular furnace by a carrier gas for evaporating the dispersant. By controlling the pH of precursor, the furnace-temperature profile and the carrier gas flow rate, the Ni/BaTiO3 particles with a core-shell structure could be prepared. In order to characterize the prepared particles, a scanning electron microscopy and an X−ray diffractometer analysis were used.
