发明名称 Dielectric ceramic composition and electronic device
摘要 A dielectric ceramic composition, comprising a main component including barium titanate, a fourth subcomponent including an oxide of R1 (note that R1 is at least one kind selected from a first element group composed of rare-earth elements having a effective ionic radius of less than 108pm when having a coordination number of nine), and a fifth subcomponent including an oxide of R2 (note that R2 is at least one kind selected from a second element group composed of rare-earth elements having a effective ionic radius of 108pm to 113pm when having a coordination number of nine). According to the composition, a dielectric ceramic composition having excellent reducing resisting property at firing, excellent temperature. dependence of capacitance after firing, and improved accelerated lifetime of insulation resistance can be provided. <IMAGE>
