Title:
MICROWAVE CERAMIC DIELECTRIC FILTER AND PROCESSING AND FORMING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/227603
Kind Code:
A1
Abstract:
Disclosed are a processing and forming method for a microwave ceramic dielectric filter and the microwave ceramic dielectric filter prepared by means of the method. The microwave ceramic dielectric filter comprises a ceramic dielectric body and a metal layer attached to the surface of the ceramic dielectric body, and the ceramic dielectric body is formed by mixing microwave ceramic powder with a ceramic forming agent at least containing a binder and then performing injection molding. The present invention can solve the problems of inconsistent dry-pressing molding size shrinkage, a local dielectric constant difference, incapability of molding complex shapes, and non-uniform green body density and the like of the microwave ceramic dielectric filter.
