Fabrication and dielectric properties of transparent PZN–BT ceramic

Transparent ceramic of 0.85Pb(Mg1/3Nb2/3)O3–0.15BaTiO3 has been successfully prepared by a two-stage sintering method using conventional raw materials. The ceramics exhibited an excellent crystallinity, high density and clean grain boundary. The transmittance keeps about4 0% from visible to near infrared regions. The frequency dependence of Tm and relaxor behavior has also been investigated using Vogel–Fulcher model and Power model.
