| 초록 | The phase formation, microstructures, sintering behavior and microwave dielectric properties of (Zr 0.8 Sn 0.2 )TiO 4 (ZST) ceramics with diff-erent amounts of La 2 O 3 /SrO additives, fabricated by the conventional solid-state reaction route, were systematically investigated. Single-phase orthorhombic crystalline structure was detected in the X-ray diffraction patterns, and the La 2 O 3 /SrO additives were found to effectively reduce the sintering temperature of ZST ceramics to 1310 o C and improve the microwave dielectric properties as long as they were supplemented in the appropriate amount (0.25wt% La 2 O 3 and 0.5wt% SrO). Low cooling rate created significant improvement in the microwave dielectric properties of the ZST ceramics. A maximum Qxf of 41,000GHz (at 5.6GHz) associated with an epsi; r of 39.56 and a tau; f of -2.65ppm/ o C was achieved for ZST ceramics with 0.25wt% La 2 O 3 and 0.5wt% SrO sintered at 1310 o C for 5h. |
