An innovative method for preparation of mullite-based refractories from aluminosilicate topaz ores is proposed in which the mineral ore is treated with ammonium fluoride; the excess silicon dioxide is removed in the form of gaseous ammonium hexafluorosilicate. The desiliconized mixture is sintered to obtain a lightweight mullite refractory with a fibrous structure.
