The invention discloses a low-glass-phase fused zirconia corundum brick with a special structure and a preparation method thereof. The fused zirconia corundum brick comprises the following chemical components in percentage by mass: greater than or equal to 32.5% of ZrO2, less than or equal to 15% of SiO2, less than or equal to 1.4% of K2O + Na2O + CaO + MgO, and the balance of Al2O3 and inevitable impurities. In addition, the content of a glass phase of the fused zirconia corundum brick is smaller than or equal to 20%, and the glass phase is divided into discontinuous blocky areas by a corundum phase in a microstructure. By optimizing the raw material ratio and the casting process, a unique microstructure is formed in the fused zirconia corundum brick, the glass phase of the fused zirconia corundum brick is uniformly divided into discontinuous areas by a dendritic corundum phase, coarse baddeleyite grains are accompanied around the discontinuous areas, the viscosity of the glass phase is remarkably improved by the structure, the flow connectivity of the fused zirconia corundum brick is effectively limited, and the fused zirconia corundum brick has good heat resistance. The product has excellent characteristics of high glass phase exudation temperature and low exudation amount, the product is particularly suitable for flame space parts of the glass melting furnace, pollution to molten glass can be avoided due to the low glass phase exudation characteristic of the product, the quality of the glass product can be improved, and the service life of the furnace can be prolonged.
