摘要：

Sr(Ti0.95Zr0.05)O-3 ceramic was sintered using x mol.% CTS (x = 0, 0.5, 1.5, 4, 7) as sintering additive for the first time. Although Sr(Ti0.95Zr0.05)O-3 ceramic could not be fully sintered even at 1420 degrees C, the densification temperature could be decreased to 1280 degrees C by using CTS. which begin melting when temperature reaches higher than 1150 degrees C. The microstructures of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). Apparent density and the dielectric properties were established at room temperature. The measuring frequency was I MHz. The microstructure and dielectric properties greatly changed depending on the amount of CTS additive. The optimum concentration to obtain nicer dielectric properties was 0.5 mol.%.
