DIELECTRIC CERAMICS THICK FILM AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A dielectric ceramics thick film is provided to improve dielectric constant and dielectric loss property and to ensure stable temperature characteristic by depositing an AgNbO3 composition and/or an AgTaO3 composition by aerosol deposition. CONSTITUTION: A dielectric ceramics thick film comprises a mixture of one or two selected from an AgNbO3 composition and/or an AgTaO3 composition. A method for preparing the dielectric ceramics thick comprises the steps of: preparing each ceramic powder of the AgNbO3 composition and/or AgTaO3 composition; and making one powder or a powder mixture of two selected from two ceramic powders in order to become aerosol and then spraying the resultant on a substrate.
