Abstract

Powders of BaTiO3, SrTiO3, and CaTiO3, were prepared from intermediate catecholate complexes, M'[Ti(C6H4O2], M' = Ba, Sr, Ca. Conversion to oxide was accomplished by heating at 600°C to produce stoichiometric powders of crystallite size, < 0.1 μm, with relatively weak agglomeration. Ultrasonic treatment of aqueous suspensions of the powders resulted in measured agglomerate sizes of less than 2–3 μm. Chemical and physical properties of the new powders are reported, together with information on sintering behaviour.
