Twelfth National Conference on Clays and Clay Minerals

Studies have been made on muscovite single crystals treated under dry and hydrothermal conditions at temperatures above 800~ The course of reaction is markedly affected by the amount of water present in the system. In the presence of a large excess of water, appreciable reaction commences at 8(~0~ with the formation of kalsilite and corundum. The kalsilite may bear an epitaxial relationship to ...
