Medium/low-sintering-temperature microwave dielectric ceramic and preparation method thereof
The invention discloses a medium/low-sintering-temperature microwave dielectric ceramic and a preparation method thereof. The preparation method comprises the following steps: by using Li2CO3, MgO, Al2O3 and TiO2 with the purity of at least 99% as original powders, weighing the materials according to the composition of Li4xMg3(1-x)Al6(1-x)Ti5xO12 (x=0.2-0.8), mixing by wet ball milling for 4 hours by using ethanol as a ball milling medium, drying, presintering in an 850-1130-DEG C air atmosphere for 4 hours to obtain a powder, adding an adhesive, granulating, compacting, and finally, sintering the ceramic at 950-1280 DEG C for 4 hours to obtain the medium/low-sintering-temperature microwave dielectric ceramic. The preparation method is simple. The prepared microwave dielectric ceramic material has the advantages of width sintering temperature range (950-1280 DEG C) and excellent microwave properties, and has application prospects in the aspect of manufacturing of resonators, microwave antennae, wave filters and other microwave devices.
