Kinetics of BaTiO ₃ and PbTiO ₃ Formation from Metallo‐organic Precursors

Abstract

Kinetics of BaTiO 3 and PbTiO 3 formation from metalloorganic precursors were studied. The fine grain size of the decomposed product and the greater degree of mixing led to very rapid kinetics of compound formation. The kinetics data were fitted to the Carter model for a diffusion‐controlled process. Formation of PbTiO 3 was modeled as a two‐stage process with a single activation energy, and the formation of BaTiO 3 as a single‐stage process.
