Abstract: Single crystals of hydrogen vermiculite have been synthesized at room temperature by ion exchange from Na-vermiculite using 1 M acetic acid for one week. The ionic conductivity was measured and shown to be much lower than that of many other monovalent cations in the same host lattice. Its enthalpy of motion is also much lower. These marked differences suggested that protonic species do not play a significant role in charge transport in these layered materials. The hydrogen vermiculite was characterized by X-ray powder diffraction and acid-base titration
