Abstract :
The phase pure dielectric ceramic with composition 0.95MgTiO3-0.05CaTiO3 (MCT) were prepared using solid state ceramic route and the effect of 60-ZnO30-B2O310-SiO2 (ZBS) on the sinterability, microstructure and dielectric properties were studied. The structural characterization using X-ray diffraction (XRD), microstructure analysis, was carried out using SEM microstructure EDAX and the microwave dielectric properties of different composite composition samples for different compositions were carried out. A ceramic composite whose sintering temperature is 1050degC, with dielectric properties epsivr = 17.7 and Qxf = 29000 when 15wt% glass was added to 0.95MgTiO3-0.05CaTiO3.
