Removal of Potassium Alters b Dimension of Muscovite

By treatment of muscovite with molten lithium nitrate at 300 176 C we have been able to remove a large portion of the interlayer potassium and observe a decrease in the apparent b axis length as a function of potassium content over the range of 88 to 07 percent potassium The b axis length of Silversheen mica a 2M1 muscovite decreases from to 197 as the potassium content
