Ga-doped zinc oxide composite functional ceramic as well as preparation method and application thereof
The invention relates to the technical field of ceramic preparation, in particular to Ga-doped zinc oxide composite functional ceramic as well as a preparation method and application thereof.The Ga-doped zinc oxide composite functional ceramic is prepared by mixing ZnO powder, Bi2O3 powder, Sb2O3 powder, Ni2O3 powder, Co3O4 powder, MnO2 powder, Al (NO3) 3 powder, TiO2 powder and Ga2O3 powder in deionized water, performing ball milling for 12 hours with a ZrO2 medium at the speed of 200 r/min, and then drying for 24 hours at the temperature of 80 DEG C; mixing the obtained dry powder with an adhesive, and then pressing into a green body; the obtained green body is heated to 600 DEG C at the heating rate of 2 DEG C/min for 2 h, and the binder is removed; the obtained green body without the binder is sintered to 1200-1300 DEG C at the heating rate of 5 DEG C/min, heat preservation is conducted for 90 min, then the temperature is reduced to the room temperature, and the zinc oxide voltage-sensitive ceramic is obtained. According to the voltage-sensitive ceramic, the problems that an existing low-voltage voltage-sensitive ceramic preparation method is difficult, and the obtained low-voltage voltage-sensitive ceramic is poor in performance are solved, meanwhile, a certain energy storage efficiency is obtained, and the zinc oxide voltage-sensitive ceramic can be used for preparing the high-performance zinc oxide voltage-sensitive ceramic. The material is a potential pressure-sensitive energy-storage composite functional material.
