High-entropy microwave dielectric ceramic with high-dielectric aluminum-doped perovskite structure and preparation method of high-entropy microwave dielectric ceramic
The invention discloses a high-entropy microwave dielectric ceramic with a high-dielectric aluminum-doped perovskite structure and a preparation method of the high-entropy microwave dielectric ceramic, and belongs to the technical field of ceramic materials in the communication field. The chemical general formula of the high-entropy microwave dielectric ceramic is (Zn < 1/6 > Ba < 1/6 > Ca < 1/6 > Sr < 1/6 > La < 1/3 >) Ti < 1-x > Al < x > O < 3 >, wherein x is equal to 0-0.1. Based on the unique effect of high entropy, the high entropy concept is introduced into the perovskite structure microwave dielectric ceramic for the first time to try to regulate and control the dielectric property, and the aluminum-doped high-entropy microwave dielectric ceramic is successfully synthesized by controlling the sintering temperature, the reaction time, the doping content and other process parameters. The dielectric constant is 74-91, the dielectric loss is 0.001-0.002, the temperature coefficient of resonance frequency is 175-217 ppm/DEG C, and excellent microwave dielectric properties are obtained. The obtained high-dielectric microwave dielectric ceramic is expected to be applied to mobile terminals, communication base stations and the like.
