Single crystals of smectite have been synthesized by quenching a hydrous melt at very high pressure and temperatures (e.g.5.5 GPa and 1600t) . The starting material was a glass with composition of a dehydrated smectite. A dominant phase of the quenched products was smectite identified by X-ray diffraction before and after intercalation of ethyleneglycol. Thin fragments of the smectite cleaved by water for electron microscopic observation were single crystals in the forms of extremely thin ribbons, laths and plates having partly hexagonal edges.
