Abstract: Treatment of a muscovite (Delamica) with molten lithium nitrate produced a lowering of the layer charge on the mica. By gradual reduction of the density of surface charge the dependence of interlamellar expansion on the attainment of a critical value of about 6.7 × 104 e.s.u./cm2 was demonstrated in a straightforward manner.
