Abstract
A perovskite ceramic composition that contains Sn, Ba, and Ti, and where the Sn content is within a range of about 0.001 parts by mol≤Sn≤about 0.999 parts by mole with respect to 100 parts by mole of the Ti. The perovskite ceramic composition can be used in a composition that further includes a rare earth element R, Mn, and Si, and optionally Mg, where proportions of the R, the Mn, the Si, and the optional Mg, satisfy R: 0<R≤about 10 parts by mole, Mn: 0<Mn≤about 5 parts by mole, Si: 0<Si≤about 5 parts by mole Mg: 0<Mg≤about 5 parts by mole with respect to 100 parts by mole of Ti.
