Phase-pure perovskite Pb(Zn x Mg 1-x ) 1/3 Nb 2/3 O 3 solid solution (PZ x M 1-x N) is obtained for x Ϲ 0.7 by heating a milled stoichiometric mixture of PbO, Mg(OH) 2 , Nb 2 O 5 , and 2ZnCO 3 ⅐3Zn(OH) 2 ⅐H 2 O at 1100°C for 1 h. Percent perovskite (f P ) with respect to total crystalline phase decreases with increasing temperature of subsequent heating then increases to 900°C for the mixtures where x Ϲ 0.8 and milled for 3 h. For mixtures with x ‫؍‬ 0.9 and x ‫؍‬ 1, f P decreases monotonically. Curie temperature increases almost linearly with increasing x up to x ‫؍‬ 0.7. The maximum dielectric constant at 1 kHz is 2؋10 4 and 1.7؋10 4 for the mixture with x ‫؍‬ 0.4 and x ‫؍‬ 0.7, respectively. The stabilization mechanism of strained perovskite is discussed.
