TLDR
In this article, phase relations and dielectric properties of ceramics in the PZN-BT-PT system are reported, and compositions with the perovskite structure, having high dielectrics constant and low temperature coefficient of capacitance, have been identified.Abstract:
The use of Pb(Zn1/3Nb2/3)O3 ceramics is restricted by the formation of a pyrochlore phase detrimental to both dielectric and piezoelectric properties. Recently it has been shown that a 6 mol% addition of BaTiO3 to PZN suppresses the formation of pyrochlore phase. Phase relations and dielectric properties of ceramics in the PZN-BT-PT system are reported here. Compositions with the perovskite structure, having high dielectric constant and low temperature coefficient of capacitance, have been identified.read more
