Abstract
Microwave dielectric properties of (Zn 1/3 Nb 2/3 ) 0.40 (Ti 1-x Sn x ) 0.60 O 2 ceramics were investigated as a function of SnO 2 content (0.15 < x < 0.30). A single phase with tetragonal rutile structure was obtained through the entire composition. The unit-cell volume of the specimens was increased with SnO 2 content, due to the larger ionic radius of Sn 4+ (0.69 A) than that of Ti 4+ (0.605 A) for octahedral site. Dielectric constant (K) of the sintered specimens was affected by the dielectric polarizability. Quality factor (Qf) was dependent on the degree of reduction of Ti 4+ ion. With an increase of SnO 2 content, the temperature coefficient of resonant frequency (TCF) of the specimens decreased due to the decrease of the octahedral distortion of rutile structure.
