Abstract

ZnO(1-x)TiO₂-xSnO₂ (x = 0.04-0.20) ceramics were prepared by conventional mixed-oxide method combined with a semi-chemical processing. 1.0% 3V₂O₅-B₂O₃ addition was used to lower the sintering temperature of ceramics. The effect of B-site substitution on phase structure and dielectric properties were investigated. The results showed that the substituting Sn for Ti accelerated the decomposition of hexagonal phase, and cubic spinel Zn₂ (Ti_1-xSn_x)O₄ solid solution formed. The best dielectric properties obtained at x = 0.12. The ZnO-0.88TiO₂-0.12SnO₂ ceramics sintered at 900°C exhibited the dielectric properties: ε = 29, tan δ = 9.86 × 10^-5. Due to their good dielectric properties, low firing characteristics, ZnO(1-x)TiO₂-xSnO₂ (x = 0.04-0.20) can serve as the microwave dielectric capacitor.
