Abstract

In the present study, production of PEROVSKITE NANOPOWDERs of the proton-conducting, electrolyte material Ba0.85K0.15ZrO3-d is conducted at room temperature by MECHANOSYNTHESIS. This is achieved with a planetary ball mill at 650rpm in zirconia vials, starting from BaO2, ZrO2 and KO2 precursors. The milling was done up to 420min and progression of reaction was monitored by XRD analysis of powder samples collected after each 60min of milling. By using XRD results, weight fraction of PEROVSKITE phase, crystallite size and lattice strain was estimated. Microstructure and chemical homogeneity were .analysed by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS) analyses respectively. Powder X-ray diffraction (XRD) reveals the formation of the PEROVSKITE phase in the early stages of milling. The PEROVSKITE crystallites are spherical in shape with an average size determined from XRD of about 20nm in agreement with transmission electron microscopy observations. EDS results shows chemical homogeneity in synthesized powder.
