MANUFACTURING METHOD FOR DIELECTRIC CERAMIC PARTICLE AND DIELECTRIC CERAMIC
To provide a method for manufacturing dielectric ceramic particles having a core-shell structure by using less expensive material.SOLUTION: A manufacturing method for dielectric ceramic particles of the present invention is the manufacturing method for dielectric ceramic particles that have core particles containing a first complex oxide with a perovskite structure at 25°C as a main component, and a shell phase that is formed on the surface of the core particle and contains a second complex oxide different from the first complex oxide as a main component. The manufacturing method for dielectric ceramic particles includes the steps of: obtaining a raw material mixture by dry blending the core particles and a raw material compound of the second complex oxide to coat the raw material compound of the second complex oxide onto the core particles; and subjecting the raw material mixture to hydrothermal synthesis treatment or solvothermal synthesis treatment. The dry blending is conducted by mechanical rotating body with a mechanism revolving at a particular angular velocity.SELECTED DRAWING: None
