Abstract: Hydrothermal BaTiO3 crystallites were coated with Bismuth solutions prepared from Bismuth metal-organics and anhydrous solvents. The Bismuth metal-organics were Bi 2-ethylhexanoate and Bi-neodecanoate. Bismuth oxide was also used as a comparison to the Bismuth solutions. BaTiO3 ceramics with either 3.0 wt % equivalent Bismuth oxide or 5.0 wt % equivalent Bismuth oxide were made by sintering the compacts between 700° C. and 1000° C. BaTiO3 ceramics that were coated by Bi-neodecanoate densified >90% theoretical as low as 800° C. for 3.0 wt % equivalent Bi2O3. Average grain sizes of 0.2-0.4 &mgr;m were observed for Bi-coated BaTiO3 ceramics, for sintering temperatures below 950° C. Dielectric K versus temperature measurements of Bismuth-coated BaTiO3 ceramics, sintered in the lower temperature ranges, showed consistently superior dielectric characteristics.
