Refractory for containment of fluoride-rich salt melts

摘要

Molten salt process for destruction of fluorine-containing waste in a molten salt such as molten sodium carbonate, and forming fluoride salts in the molten salt bath. The destructive phase change of conventional alpha-alumina refractory of the molten salt retaining vessel in the presence of such fluoride salts is avoided according to the invention by employing phase change resistant beta-alumina refractory bricks.
