Without any calcination involved, pure Zn0.5Ti0.5NbO4 (ZTN) and Ni0.5Ti0.5NbO4 (NTN) phases could be obtained successfully after sintering the pellets with x=0.5, y=1. Pellets with >99% of theoretical density could be obtained. Microwave dielectric properties Q×f=35000GHz, εr =32.6, and τf=-48.38 ppm/oC in ZTN sintered at 1200oC for 2 h and Q×f=35000GHz, εr =32.6, and τf=-48.38 ppm/oC in NTN sintered at 1170oC for 6 h were found. As TiO2 was added into ZnNb2O6 and NiNb2O6 τf values approach 0 ppm/oC could be found. Microwave dielectric properties Q×f=19000GHz, εr =49.9, and τf =0 ppm/oC in pellets with x=0.6 and Q×f=18700GHz, εr =29.3, and τf =-0.05 ppm/oC in pellets with y=0.1 were obtained. With CuO addition, the sintering temperature was lowered to 1070oC for ZTN and 1130oC for NTN. The microwave dielectric properties Q×f=32000GHz, εr =31.5 and τf =-40.89 ppm/oC for ZTN were found. Q×f=3579GHz, εr =53.2 and τf =+93.81 ppm/oC for NTN were found. Yi-Cheng Liou 劉依政 2007 學位論文 ; thesis 131 |
