Abstract

Effect of B₂O₃ and BaB₂O₄ addition on microwave dielectric characteristics and sintering behaviours of BaTi₄O₉ ceramics were investigated. When B₂O₃ was added, bulk density of the sintered sample decreased as the content of B₂O₃ increased. B₂O₃ addition induced complex reaction with BaTi₄O₉ and resulted in the development of second phases such as Ba₂Ti₉O₂₀, BaTi(BO₃)₂ and TiO₂. When BaB₂O₄ was added, however, relative density increased and the second phases of Ba₂Ti₉ O₂₀ and BaTi(BO₃)₂ were produced. Dielectric characteristics of BaTi₄O₉ were also discussed from the viewpoint of bulk density, microstructure and second phases.
