Low Temperature Firing of MgTiO₃-CaTiO₃ Microwave Dielectric Ceramics Modified with B₂O₃ or V₂O₅

Effect of B2O3 addition on the sintering temperature and microwave dielectric properties of Zn2SiO4 ceramics

“…[2][3][4][5] However, the added glass exists as an amorphous phase in the specimens, which deteriorates the Q × f value of the specimens. [6][7][8][9][10][11] Although some materials have a high Q × f value, they generally show a large negative temperature coefficient of the resonant frequency (τ f ).…”

Low temperature sintering and microwave dielectric properties of (Mg0.7Zn0.3)0.95Co0.05TiO3 ceramics with BaCu(B2O5) additions

“…Recently, low temperature co-fired ceramic (LTCC) multilayer devices, composed of alternating dielectric ceramics and internal metallic electrode layers, have been extensively investigated for the miniaturization of microwave dielectric components [1][2][3]. LTCC multilayer devices consist of alternating microwave dielectric ceramics and internal metallic electrode layers.…”

Low temperature sintering of BaCu(B2O5)-added BaO–Re2O3–TiO2 (Re=Sm, Nd) ceramics

“…4,5 Moreover, a small amount of oxide with a low melting temperature was also used as an additive to decrease the sintering temperature of microwave dielectric materials. 6 BaO-Re 2 O 3 -TiO 2 ceramics (Re = Sm, Nd) are known to have good microwave dielectric properties. [8][9][10][11][12] However, their high sintering temperature of approximately 1350 • C needs to be decreased for application to LTCC technology.…”
