Abstract

BaCu(B₂O₅) (BCB) additive was used to decrease the sintering temperature of the BaTi₄O₉ ceramics. The amount of Ba₄Ti₁₃O₃₀ second phase increased with the addition of BCB, whereas that of the BaTi₄O₉ phase decreased. The bulk density and dielectric constant (ε_r) considerably increased with the addition of BCB. An increase in the Q-value was also observed for the BaTi₄O₉ ceramics with a small amount of BCB. Good microwave dielectric properties with values of ε_r = 32, Q × f = 10800 GHz and τ_f = 32 ppm/°C were obtained in the BaTi₄O₉ ceramics with 12.0 mol % of BCB sintered at 875 °C for 2 h.
