| Abstract: | Two-phase crucibles made of Pb(Zr,Ti)O3 with small additions of either PbO or (Zr x Ti 1-x )O2, which provide atmospheres of constant PbO activity, permit study of intrinsic nonstoichiometry by thermogravimetry. The width of the single-phase region can be determined by alternate equilibration of a sample with crucible atmospheres of high and low PbO activity. The width of this region for Pb(Zr0.5Ti0.5)O3 is 2.48 mol% PbO at 1100°C. |
