PROTON CONDUCTIVITY IN PURE AND DOPED KH2PO4.

Abstract

The electrical conductivity of pure and KHSO4-doped KH2PO4 was measured over a wide range of temperatures under the equilibrium water vapor pressure. For pure KH2PO4, the conductivity perpendicular to the C axis is given by log sigma = -1.17 - 2760/T, T < 180C; log sigma = 2.0 - 3900/T, T > 180C. The conductivity of doped crystals is 0.00000106 C/ohm/cm, where C is the mole fraction of sulphate. The results are discussed in terms of the defects possible in KH2PO4. (Author)
