Dielectric and pyroelectric properties of ceramics PbZr1-xTixO3 (PZT) in the concentration range 0.01<x<0.08 were investigate. As a matter of record it was found that in the PZT there is a region wherein appear three inhevent for the entire family of perovskite instabilities of original cubic lattice. It is shown that the antiferroelectric phase in PZT exists up to x=0.07. Studies of a composition with x = 0.08 in the temperature range -200ºC<T<300ºC had not revealed existence of antiferroelectric phase that makes evident the existence of vertical boundary between the Pbam and R3c phases.
