Dielectric ceramic composition, dielectric ceramic compact and electronic component including the same |
摘要 |
A dielectric ceramic composition for radiofrequency applications has a crystalline primary component having a perovskite crystal structure, and an auxiliary component. The crystalline primary component is represented by the formula:wherein Me is at least one of Ca and Sr; Ln is a rare earth element; Ma is at least one of Mg and Zn; Mb is at least one of Sn and Zr; x represents a mole fraction of Ln(Ma1/2Mb1/2)bO(3+3b/2); and a and b represent molar ratios, wherein 0.95<=a<=1.05, 0.9<=b<=1.05, and 0.3<=x<=0.5. The auxiliary component includes B and Si. The composition can be sintered at 1,000° C. or less. An electronic component includes a ceramic element of the dielectric ceramic composition and conductors provided in the interior of the ceramic element.
