... molten beryllium and sodium chloride salt-mix is a low-temperature commercial process. Conversion of beryl ore into beryllia precedes the fused salt electrolysis, and several purification techniques are followed to produce high-purity beryllium metal. A new modified beryllium chloride-beryllium...

... compounds involving V 2 O 5 -Na 2 O and/or V 2 O 5 -Na 2 SO 4 systems. Molten vanadate compounds flux away the oxide scales formed on the metal, thus causing rapid corrosion attack. The corrosion mechanism is essentially hot corrosion involving a fused salt in an oxidizing environment. The hot corrosion...
