The invention relates to a wear-resistant and thermally stable alumina coating carrier, which mainly solves the technical problem that an alumina coating is severely worn and even cracked and stripped under the action of a high temperature and water-vapor-containing air flow for a long time in the prior art. The alumina coating of the wear-resistant and thermally stable alumina coating carrier comprises at least one of gamma-Al2O3, delta-Al2O3 and theta-Al2O3 serving as a main body, at least one of samarium, thulium, yttrium, niobium, thorium, lanthanum, cerium and the like serving as a stabilizer, and at least one of calcium silicate, magnesium aluminate, zirconium aluminate, wollastonite, diopside, perlite and clay serving as an auxiliary agent, and a kernel is at least one carrier of alumina, silica, cordierite, spinel, sillimanite, andalusite and kyanite. Through the technical scheme, the problem is well solved, and the invention can be used for the industrial production of preparing the wear-resistant and thermally stable alumina coating carrier.
