Title:
CERAMIC MATERIAL AND METHOD FOR FABRICATING SAME, AND RESONATOR, FILTER, AND REMOTE RADIO DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/113221
Kind Code:
A1
Abstract:
The present invention provides a BaTi4O9-based microwave dielectric ceramic material and method for fabricating same, and a resonator, filter, and remote radio device; the method for fabricating the dielectric ceramic material comprises the steps: preparing a mixture, the mixture at least comprising a BaTi4O9-based ceramic powder and an organic binder; injection-molding the mixture to obtain a green body; performing non-polar solvent extraction debinding and then thermal debinding on the green body; sintering the thermally debound green body to obtain a BaTi4O9-based microwave dielectric ceramic. In the method for preparation, a BaTi4O9-based dielectric ceramic is injection-molded, such that a dielectric ceramic material having uniformly distributed density and size and having highly accurate size after sintering is obtained; the cost of the material is low, and the preparation process is simple. In comparison with resonators produced by dry pressing, the invention has a high quality-factor Q×f value and stable performance.
