Two‐phase crucibles made of Pb(Zr,Ti)O 3 with small additions of either PbO or (Zr x Ti 1‐x )O 2 , 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(Zr 0.5 Ti 0.5 )O 3 is 2.48 mol% PbO at 1100°C.
