Summary:The invention relates to a high-aluminum glass clarificant. The high-aluminum glass clarificant comprises 3-25 wt% of sodium nitrate, 15-30 wt% of tin oxide and 50-80 wt% of molybdenum tungsten tailings, wherein the sodium nitrate is industrial grade sodium nitrate having a weight content of 99.50% or more. A preparation method of the high-aluminum glass clarificant comprises the following steps:grinding dried molybdenum tungsten tailings to a particle size of 0.10 mm, and then uniformly mixing the ground dried molybdenum tungsten tailings with sodium nitrate and tin oxide according to aboveweight percentages to prepare the mixed clarificant. The clarificant is obtained by mixing the sodium nitrate, tin oxide and molybdenum tungsten tailings in different proportions, so the high temperature viscosity of the high-aluminum molten glass is reduced, the mechanical properties and the chemical stability of the glass are improved, and the clarificant can be used to produce high-aluminum glass in order to further imp
