Synthesis and Microwave Dielectric Properties of $La(Zn_{1/2}Ti_{1/2})O_3$
The dielectric properties at microwave frequencies of B site complex perovskite La(Zn1/2Ti1/2)O3 which has +3 ion in A site were investigated. maximum Q*F value of the specimens was 59000 dielectric constant 34, temperature coefficient of resonant frequency -52 ppm/$^{circ}C$. XRD pattern of the sintered specimen shows (111) ssuperlattice reflection which indicates Zn and Ti cation ordering.
Key words: Complex perovskite, $La(Zn_{1/2}Ti_{1/2})O_3$, Dielectric properoties, Microwave
