Mise en solution par fusion alcaline

The technique uses fluxing agents :

  • Mixing: fluxing agent/sample, lowers the melting point of the sample.
  • The main fluxing agents contain borates: LiBO2 / sample powder.

Melting is generally done in graphite crucibles using a magnetic induction furnace.

The obtained bead is dissolved in an acidified solution (HNO3 1%). The total volume is 200ml. It results in a dilution factor of 2000.
