The reaction between molten lithium nitrate and muscovite does not go to completion in a single treatment because of the equilibrium restriction imposed by the presence of potassium in the melt. An apparatus consisting of a stainless steel vessel with a porous stainless steel filter, valve and vacuum connections was designed to eliminate this restriction and to provide for more complete removal of the equilibrium melt in each successive treatment.

Macroscopic swelling of the muscovite in the molten lithium nitrate was observed after prolonged treatment. x-Ray diffraction examination of samples of solidified melt revealed intracrystalline swelling in the muscovite.
