| 简介 | A high dielectric material having a high dielectric constant which is especially useful as a material for high-capacitance capacitors is disclosed. The high dielectric material is composed of a sintered body of a rare earth sulfide which has a crystal structure of tetragonal beta-phase, a chemical composition of Ln2S3 (wherein Ln represents a rare earth metal), a frequency domain within the range of 0.5-1, 000 kHz, and a relative dielectric constant of more than 1, 000 at room temperature. | ||
