Abstract

The phase assemblage and dielectric properties of Nd(Zn_1/2Ti _1/2)0₃ (NZT) and La(Zn_1/2Ti _1/2)O₃ (LZT) ceramics prepared via the mixed-oxide route were investigated in this study. Single-phase ceramics were synthesised for both LZT and NZT at every sintering temperature below 1500°C, at which temperature traces of (La,Nd)TiO₅ were apparent on pellet surfaces. Both compositions also have promising dielectric properties. In particular, LZT has ∞_r ≈ 34, Q_f ≈ 36,000, and τ _f = -70 MK^-1; while NZT has ∞_r=36, Q _f ≈ 42,300, and τ_f = -47 MK^-1. Clearly these materials show potential as filters for mobile microwave telecommunications.
