“…A further increase in the thermal energy makes the water molecules free and finally causes dehydration. A similar mechanism was observed by Desai and Ramana [29] for lead nitrate phosphate dihydrate.…”

conductivity (~) and the relative permittivity (~) were accurately measured as a function of temperature in the range 300 < T< 450 K for ammonium oxalate monohydrate (AOX), (NH4)2 C204H20 and potassium oxalate monohydrate (POX), K2C204H20. Differential thermal analysis (DTA), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) from 300 K up to 520 K were also performed for each compound. The data of the electrical parameters combined with the DTA and/or DSC thermograms suggest the existence ot; a possible change in the electrical conduction at 350 K for AOX and at 355 K for POX. Like most hydrogen-bonded molecules, the charge carriers may be protons and the electrical conduction is therefore protonic. At somewhat higher temperatures, dehydration and/or decomposition takes place in each compound and is reflected as a sudden loss in weight in the TGA plot.

“…Similar behaviour was observed in rubidium hydrogen tartrate single crystal and polycrystalline samples [28] and also in lead phosphate nitrate dihydrate [29]. However, measurements on single crystals, in addition to coulometric studies are needed as confirmative tools for the suggested conduction mechanism.…”
