Abstract
  • Barium titanate powders have been synthesised using a Low Temperature Aqueous Synthesis (LTAS) method in both batch and Segmented Flow Tubular Reactors. For similar stoichiometries the SFTR powder shows a much lower degree of aggregation with 80% particles < 100nm for the SFTR and only 57% < 100nm for the batch case. Specific surface areas for the SFTR powder are also higher at around 59m(2)/g compared to 38m(2)/g for the batch powders indicative of primary particle sizes of 24 mn (SFTR) and 31 run (batch). After freeze drying, redispersion and slip casting the SFTR powder gives improved sintered densities (95.5 from 93.25%) the sintered microstructures are very similar. (literal)
