Kinetics of BaTiO3 and PbTiO3 Formation from Metallo-organic Precursors

Kinetics of BaTiO3 and PbTiO3 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....

Zusammenfassung:Kinetics of BaTiO3 and PbTiO3 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 PbTiO3 was modeled as a two‐stage process with a single activation energy, and the formation of BaTiO3 as a single‐stage process.
