The invention belongs to the technical field of refractory materials and discloses a high-toughness refractory material which is mainly prepared from the following raw materials in parts by weight: 100 parts of aluminum oxide, 30-40 parts of magnesium oxide, 1-2 parts of niobium pentoxide, 0.5-1 part of tantalum pentoxide, 1-3 parts of a powder adhesive and 0.2-0.5 part of a molding adhesive. When the refractory material is prepared, a prepared blank is relatively good in mechanical property, not liable to crush and the like and relatively high in pass percent; the refractory material disclosed by the invention is relatively high in breakage toughness, the service life of the refractory material is ensured, and meanwhile the reliability of the refractory material can be also ensured.
