Abstract

The invention discloses a preparation method of a microwave dielectric ceramic material and a dielectric ceramic block. The method for preparing the microwave dielectric ceramic material comprises thefollowing steps of: providing raw materials corresponding to calcium carbonate, samarium sesquioxide, aluminum oxide and titanium dioxide; adding an organic solvent and grinding balls, and carrying out primary ball milling; drying the slurry obtained by the primary ball milling, and calcining to obtain a ceramic body; crushing the ceramic body, adding an organic solvent and grinding balls, and carrying out secondary ball milling; drying the slurry obtained by the secondary ball milling; mixing the obtained powder with a binder to form slurry, and granulating; carrying out dry pressing moldingin a mold; and removing the binder and sintering again. The microwave dielectric ceramic material prepared by the method is mainly composed of calcium carbonate, samarium sesquioxide, aluminum oxideand titanium dioxide, and has the advantages of low dielectric constant, low loss and near-zero temperature coefficient. Therefore, the microwave dielectric ceramic material provided by the inventionhas improved microwave dielectric properties.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for manufacturing a microwave dielectric ceramic material and a dielectric ceramic block for 5G communication technology. Background technique [0002] The rapid development of microwave communication technology (such as 5G communication technology) puts forward higher requirements on the performance of microwave devices. Traditional metal resonators are bulky and heavy, which limits the performance of microwave devices. Microwave dielectric ceramic materials usually need to have a high dielectric constant, which can be made into various microwave devices to meet the requirements of miniaturization and low loss of filter units. [0003] The present application proposes a novel method for preparing a microwave dielectric ceramic material, and the microwave dielectric ceramic material prepared according to the method has improved microwave dielectric properties. ...
