CHARACTERIZATION OF (Mg0.5ZN0.5)TiO3 CERAMICS AS MATERIAL CANDIDATES FOR DIELECTRIC RESONATOR AT MICROWAVE FREQUENCY

MgTiO3 ceramic is one of the dielectric materials used as a signal generator (dielectric resonator) in microwave telecommunication devices. This research intended to explore possibility new composition MgTiO3-based ceramic, i.e. (Mg0.5Zn0.5)TiO3 (abbreviated MZT05) resonator material. The aim was characterize resonant frequency ceramics on microwaves (measured using spectrum analyzer), and results were correlated structure (X-Ray Diffraction, XRD), microstructure (Scanning Electron Microscope, SEM), bulk density data (Archimedes method) ceramics. work begun by compacting MZT05 crystalline powder cylindrical shape with diameter 5 mm uniaxial die press produce tablets. tablets sintered at 1300 ºC variations holding times 6, 8, 10 h structural revealed that phase identified main ceramics, (96.32-98.70) %molar. increased increasing sinter time, from 2.75 g/cm3 (6 h), 2.84 (8 h) 2.99 (10 due increase grain size 919.75 nm 1090.62 1180.72 accompanied decrease pore 924.14 917.05 800.22 h). produced frequencies 5.07–5.08 GHz, which implies are proven be potential candidates for frequencies, especially 5.07-5.08 GHz. varying time seems not influence because variation similar frequencies.
