发明名称 Method of producing a powder, powder, and multilayered ceramic capacitor using the same
摘要 An object of the present invention is to make a core/shell structured powder different in composition between the inside the particle and the surface thereof before sintering, so that it is possible to sinter the powder at lower temperature and give a core/shell structured powder having a shell portion uniform in thickness after sintering. Another object of the present invention is to provide a multilayered ceramic capacitor having a longer lifetime, by preparing the multilayered ceramic capacitor by using a powder having a core/shell structure different in composition between the inside the particle and the surface thereof before sintering. The method of producing a powder according to the invention is a method of producing a powder by synthesizing particles in the liquid containing a raw material, wherein particles different in composition at least between the inside the particle and the surface thereof are obtained by adding a composition to be incorporated as a component of the particles to the liquid during the synthetic process so that the composition of the liquid changes continuously or intermittently.
