The invention relates to the technical field of functional
ceramic materials, and discloses complex-
phase gradient isomeric
zinc spinel-based composite activated
zinc oxide, a preparation method thereof and a
ceramic glaze, and the preparation method comprises the following steps: mixing
zinc oxide, aluminum
oxide,
silicon oxide,
magnesium oxide and
rare earth oxide in proportion to obtain a mixture, adding the mixture and an alkoxy compound into a
solvent, and dispersing to form nano precursor
slurry; carrying out reduction-oxidation
calcination treatment on the obtained nano precursor
slurry to obtain a calcined product; and carrying out hydration treatment on the obtained calcined product to obtain the complex-
phase gradient isomeric zinc
spinel-based composite activated zinc oxide. By implementing the preparation method, the obtained complex-
phase gradient isomeric zinc
spinel-based composite activated zinc oxide contains a zinc oxide phase and a spinel phase, is low in high-temperature lattice
distortion rate and has super
wear resistance, and a
rare earth element R is introduced, so that the catalytic activity of the zinc oxide is improved, the degradation rate of the zinc oxide to
formaldehyde and
toluene is increased, and the
antibacterial property of the zinc oxide is also improved.
