The Dissolution of Thorium Metal and Thorium Dioxide in HNO3 - HF and HNO3- ( NH4 ) 2 SiF6 Mixtures
Description:
Abstract. A satisfactory method has been found for dissolving thorium metal and thorium oxide in heat-treated 25-12 stainless steel vessels without excessive corrosion of the vessels. The dissolution medium consists of strong HNO3 containing a small amount of fluoride or fluo-silicate. the fluoride required has no harmful effects on a subsequent solvent-extraction step for a separation of uranium isotopes from the dissolved thorium.
