The invention belongs to the technical field of ceramic glazes, and particularly relates to an ultrahigh-temperature wear-resistant corrosion-resistant ceramic glaze and a preparation method and application thereof. The ceramic glaze is prepared from quartz powder, potassium feldspar, kaolin, wollastonite, aluminum oxide, lanthanum oxide, molybdenum trioxide, cerium dioxide, zirconium dioxide andyttrium oxide. The ceramic glaze has a wide glaze firing range, can be fired at a high temperature of 1450-1600 DEG C, has a high use temperature, and can be used at a temperature of 1250 DEG C or below. By introducing lanthanum oxide, molybdenum trioxide, cerium dioxide, zirconium dioxide, yttria and other components, the microstructure of the ceramic glaze layer is effectively improved, the hardness of the ceramic glaze layer is enhanced, the wear resistance and the corrosion resistance of the glaze layer are improved, the firing range of the glaze is widened, the friction coefficient of theglaze layer is reduced, a
