Influence on Dielectric Properties and Evaporation of PbO According to Substituting $Nd^{3+}$ for $Pb^{2+}$ in $Pb(Mg_{1/3}Nb_{2/3})O_3$ System

ABSTRACT

Influence of Nd3+ substitution for Pb2+ on the dielectric properties and the PbO evaporation according to substituting Nd3+ for Pb2+ in Pb(Mg1/3Nb2/3)O3 system ceramics have been investigated. The dielectric constant at the curie temperature and evaporation of PbO were decreased with increase of Nd3+ amounts. The percentage of PbO evaporation was 2.5wt% in the PMN system substituted Nd3+ for Pb2+, while it was 3.7wt% in the PMN system.
