  • Abstract
    The microwave dielectric properties of rutile (Zn1/3B2/3) x(TiySn1-y)1-xO2 (B=Nb5+,Ta5+, 0.05 les x les 0.35, y=0.2, 0.8) were investigated with structural characteristics. A single phase with tetragonal rutile (P42/mnm, No.136, Z=2) structure was obtained through the entire range of compositions. With an increase of (Zn1/3B2/3)O2 content, the dielectric constant (K) of sintered specimens with (Ti0.2Sn0.8)O2 increased, while that of the specimens with (Ti0.8Sn0.2)O2 decreased. The temperature coefficient of resonant frequency (TCF) of sintered specimens was dependent on oxygen octahedral distortion and/or cations bond valence of rutile structure. Quality factor (Qf) was dependent on (Zn1/3B2/3)O2 content, and the specimens with (Ti0.2Sn0.8)O2 showed larger Qf value than that with (Ti0.8Sn0.2)O2 for the same content of (Zn1/3B2/3)O2.
