Method of producing a powder, powder, and multilayered ceramic capacitor using the same

A method of producing a powder comprising synthesizing particles in a liquid comprising raw materials of two or more elements,

• wherein particles different in composition at least between the inside the particle and the surface thereof are obtained by supplying a composition (1) to be incorporated as a component of the particles to the liquid so that the composition of the liquid changes continuously or intermittently during the synthetic process, wherein
• the obtained particles are oxides having a perovskite structure,
• the oxide having a perovskite structure is an oxide represented by ABO3, A represents at least one element selected from the group A consisting of barium, strontium, lead, rare-earth metals, magnesium, potassium, and sodium, and B represents at least one element selected from the group B consisting of titanium, zirconium, and niobium,
• at least a raw material comprising group-A element A1 and a raw material comprising group-B element B1 are incorporated in the liquid in advance before initiation of synthesis,
• the composition (1) comprises a raw material comprising another group-A element A2 different from the A1 element, and
• the raw material comprising element A1 and the raw material comprising element B1 are reacted and thereafter the composition (1) is supplied to the liquid and reacted in the synthesis process, and
• the particles having a composition of A1B1O3 comprising the A1 and B1 elements as the principal components inside the particle and a composition of A2B1O3 comprising the A2 and B1 elements as the principal components in the surface of the particle are obtained.
