• 要約等: Effects of liquid phase on microwave sintering with a frequency of 2.45 GHz of BaTiO<SUB>3</SUB> ceramics were investigated. The additives to form the liquid were BaCO<SUB>3</SUB>, H<SUB>3</SUB>BO<SUB>3</SUB> and BaB<SUB>2</SUB>O<SUB>4</SUB>. Addition of the liquid phase in microwave sintering promotes densification of BaTiO<SUB>3</SUB> ceramics significantly, and densified ceramics were obtained by lower applied power and shorter processing time. Furthermore, electric resistivity of dense ceramics with BaCO<SUB>3</SUB>+2H<SUB>3</SUB>BO<SUB>3</SUB> addition was different by sintering techniques, and a sample obtained by microwave sintering showed the dielectric, while one obtained by conventional sintering showed the semiconducting properties. Such different result is considered to be relating to presence of liquid phase with strong microwave absorption.
