Phase formation in PZT phosphorus-doped ceramics

Abstract:

The surface modification of lead zirconate titanate ceramics with phosphate ester left a phosphorus residue absorved onto the particle surface. During the sintering processes, this surface layer reacts with the PZT to form lead rich compounds, as Pb3(PO4)2 and Pb 4(P2O9). The formation of such a compounds may be the responsible for the grain growth inhibition observed in PZT modified ceramics, as well as the lead loss reduction.
