Abstract

Analysis of microstructure of Strontium titanate (SrTiO3) phase obtained by milling and annealing of SrCO3 and TiO2 precursors. However, the material properties for strontium titanate require a careful control of crystallite structure as well as microstructure design to meet a specific application. The mixture of strontium carbonate (SrCO3) and tintanium oxide (TiO2) powders was used to obtain SrTiO3 phase by using vibrator ball mill with ball to powder ratio 10:1 and heat treatment processes. The size of powder particles was determined by a laser particle analyzer (PSA). The X-ray diffraction methods were used for qualitative, quantitative phase analyses and for crystallite size and lattice distortion determination. The milling process of strontium carbonate and tintanium oxide mixture causes decrease of the mean particle size and crystallite size of involved phases. The X-ray diffraction investigations of SrCO3 and TiO2 mixture milled for 60 hours and annealed at 900°C with 24 h of holding time enabled the identification of SrTiO3 phase. Annealing the sample of the particles at 900 0C has resulted in a dense compact and promoted the formation of particles containing nanocrystallites. The crystallite-growth samples of SrTiO3 phase were dependent on temperature and time of their annealing.
