Synthesis of PbTiO3 by use of polymeric precursors

Lead titanate powders were synthesised through the use of polymeric precursors according to the Pechini Process. The polymeric precursor was calcined at temperatures ranging from 300 to 600 C for 1 or 2 h. XRD showed that lead titanate crystallises from the precursor at temperatures as low as 400 C....

Summary:Lead titanate powders were synthesised through the use of polymeric precursors according to the Pechini Process. The polymeric precursor was calcined at temperatures ranging from 300 to 600 C for 1 or 2 h. XRD showed that lead titanate crystallises from the precursor at temperatures as low as 400 C. No intermediate carbonate phase was detected by FTIR or by XRD. A powder with mean particle size of 150 nm was obtained after calcination of the precursor at 600 C for 1 h. 15 refs.
