A new technique for the separation of metals such as Bi and Pb from borate-based glasses has been proposed, in which metal nitrides such as AlN are added to the glasses containing Bi or Pb ions and melted at temperatures of around 1200oC. Metal nitrides act effectively as reducing reagents for Bi and Pb ions, producing the precipitation of those metals. The relation between the amount of metal nitride additions and the amount of precipitated metals is examined.
This new technique will apply for the recovery of metals in waste glasses and for the fabrication of metal nano-particles in glasses.
