Grain Size Regulation and Dispersion Improvement of Barium Strontium Tiatanate Nanaopowder
Abstract: Barium strontium titanate nanopowder was synthesized by hydrothermal method. The function of dispersant on the particle size regulation and the improvement of powder agglomeration were studied. Effect of annealing on the dispersion of the nanopowder was also investigated. The results turned out that the addition of oleic acid could effectively decrease the particle size of Barium strontium titanate powder, and the smallest particle size could be achieved with the addition of 0.5 ml oleic acid which is about 15 - 25 nm. The dispersibility of the powder was obviously improved by post annealing of the hydrothermal synthesized powder, while the particle size was kept unchanged.
