Dielectric Properties of BaTi₅O₁₁ Ceramics at Microwave Frequencies

Abstract:

Microwave dielectric properties of BaTi₅O₁₁ ceramics prepared by solid-state method with various calcining temperatures and sintering temperatures have been discussed. The ε_r value of 42.8, the Q×f value of 44,000 GHz, and the τ_f value of 42.4 ppm/oC were obtained for BaTi₅O₁₁ ceramics sintering at 1100oC for 4 h. BaTi₅O₁₁ is proposed as a suitable material candidate for application in high selective microwave ceramic passive components.
