Graphite tailing-based microwave dielectric ceramic material and preparation method thereof
The invention discloses a graphite tailing-based microwave dielectric ceramic material which is prepared by sintering the following raw materials in percentage by mass: 45-50% of graphite tailing powder, 18-20% of Al2O3 powder, 10-18% of BaCO3 powder, 12-20% of SrCO3 powder and 2-5% of TiO2 powder. The invention also discloses a preparation method of the graphite tailing-based microwave dielectric ceramic material. The preparation method comprises the following steps of pretreating graphite tailing powder, mixing the BaCO3 powder, the SrCO3 powder, the Al2O3 powder and the graphite tailing powder, and barreling the mixed powder by a dry method, calcining the powder subjected to barreling, mixing the calcined powder with TiO2 powder, and carrying out wet ball milling, and carrying out granulation molding on the dried powder, and sintering to obtain the ceramic material. The graphite tailing-based microwave dielectric ceramic material prepared by the invention not only provides a new way for the utilization of graphite tailings, but also provides a feasible solution for the microwave dielectric ceramic material for 5G mobile communication.
