Shukla, Swapna Samir (2011) Synthesis and dispersion of barium stannate nanopowders. BTech thesis.
The present work deals with the synthesis and dispersion of Barium Stannate (BaSnO3) nanopowders. BaSnO3 was prepared through a novel co-precipitation route using SnCl4.5H2O and BaCl2.2H2O as the starting precursors and subsequent calcinations at 1100oC. X-Ray diffraction pattern indicates the presence of single phase of BaSnO3 which was supported by FTIR analysis. The lattice parameter was found to be 4.12 Å. The data obtained from BET surface area indicates that the particle size is near about 250nm at pH 13. Isoelectric point (IEP) of nanopowder suspension was determined prior to the addition of different dispersants. The isoelectric point was found to be at pH 4.95 and the electrolyte weight percentage was optimized for stable dispersions.
