Effect of Various Dopants on (Zr0.8Sn0.2)TiO4 Microwave Dielectric Ceramics by a Reaction-Sintering Process
碩士 === 崑山科技大學 === 電子工程研究所 === 94 === (Zr0.8Sn0.2)TiO4 ( ZST ) microwave ceramics with B2O3, NiO, CuO, La2O3 and ZnO addition and prepared by a reaction-sintering process were investigated. The mixture of raw materials was pressed and sintered into ceramics without any calcination stage involved. Den...

With CuO addition, pellets of >97% theoretic density were obtained at 1130oC/4 h sintering. Microwave properties Qxf=38,000 GHz, εr=24 and τf=2.5ppm/oC were found in ZST with CuO added. In La2O3 doped ZST, Qxf=46,000 GHz, εr=26.8 and τf=-2.3ppm/oC was observed at 1450oC/6 h sintering. ZST of Qxf=20,000 GHz, εr=30.3 and τf=0ppm/oC was obtained with ZnO added and sintered at 1380oC/6 h. Yi-Cheng Liou 劉依政 2006 學位論文 ; thesis 91 |
