Thermal expansion of ammonium pertechnetate and ammonium perrhenate

Journal of Solid State Chemistry, 2019
Abstract The thermal expansion of NH4TcO4 and NH4ReO4 between 97 and 500 K has been established using variable temperature synchrotron X-ray diffraction. Both oxides display a tetragonal scheelite-type structure over the temperature range. The observed anomalous thermal expansion is associated with disorder in the orientation of the NH4 groups and ...

Energetics of ammonium cyanide and of some ammonium halides

Transactions of the Faraday Society, 1970
An analysis of the energetics of the structure of ammonium cyanide has permitted a more detailed description of this substance than has been given hitherto. The crystal energies of ammonium chloride and ammonium bromide have been revised during the calculations, and a more precise value for the enthalpy of formation of the gaseous ammonium ion has been

Phase transitions in ammonium and deutero-ammonium halides

Radiation Effects, 1970
Abstract Recent results obtained by dilatometric, calorimetric, X-ray, and NMR methods for the phase transitions in ammonium and deutero-ammonium halides are reported. The dilatometric observations on the kinetics of the transitions I-II of NH4Cl and NH4Br, and the effects of deuteration on the I-II transformation temperature and volume change, and on ...
