Generation of metal titanate powders by spray pyrolysis using single-source precursors

Abstract

Crystalline, phase-pure, submicrometre sized PbTiO₃ and BaTiO₃ particles have been produced via aerosol decomposition of single-source mixed metal–organic precursors A(O₂CCMe₂O)₂Ti(OPri)₂(A = Pb or B) at 600–900 °C. The particles were hollow, ranged in size from 0.1 to 1 µm and consisted of 30–50 nm crystallites.
