Effect of ZnO additive on sintering behavior and microwave dielectric properties of 0.95MgTiO3–0.05CaTiO3 ceramics

Dielectric characteristics of the (1−x)Mg2TiO4–xSrTiO3 ceramic system at microwave frequencies

“…On the other hand, high quality factor (inverse of the dielectric loss, Q = 1/tan ␦) would play a more prominent role instead, since Q × f is almost constant in the microwave region [2]. It explained the research on high-Q dielectric materials, such as the MgO-TiO 2 binary system, has brought much more attention recently [3][4][5][6]. Among these compositions, MgTiO 3 and Mg 2 TiO 4 are both recognized as good candidates for high frequency applications.…”

Sinterability and microwave dielectric properties of 0.95MgTiO3–0.05CaTiO3–glass ceramic composites

“…The rapid growth in the field of microwave satellite communication systems such as cellular phones and global positioning systems (GPS) demand the developments of variety of microwave resonating materials [1][2][3][4]. These dielectric resonators (DRs) help to miniaturize the size and cost of the microwave electronic devices to significant extent.…”

Effect of TiO2 content on the microwave dielectric properties of BaO-ZnO-TiO2 ceramics

“…All the samples showed highly compact microstructure with crystal grains in dense contact, which was attributed to flux effect of excessive ZnO in sintering process. During sintering the intermediate products with low melting point formed liquid phase, in which ions can transfer easily, so the densification was improved [6,11]. And very few pores could be observed in Figures 3(a) and (d).…”
