Microwave dielectric ceramic material based on microwave cold sintering and low-carbon preparation method

The invention discloses a microwave dielectric ceramic material based on microwave cold sintering and a low-carbon preparation method thereof.The low-carbon preparation method comprises the steps that firstly, ceramic and a liquid phase are mixed for 5-60 minutes, and after mixing, the mass fraction of ceramic powder is 50%-95%, and the balance is the liquid phase; 2, performing tabletting treatment on the mixture in the step 1; and step 3, putting the tableted product into a microwave sintering furnace for sintering at the sintering temperature of 100-1000 DEG C, the heating rate of 1-50 DEG C/min and the heat preservation time of 10-300 minutes to obtain the microwave dielectric ceramic. And compared with traditional high-temperature sintering, the preparation time of the sample is greatly shortened, the sintering temperature of the sample is reduced, high densification can be achieved, and the microwave dielectric property of the sample can be comparable with or even better than that of the sample prepared
