STRUCTURE AND THERMOCHEMICAL REACTIVITY OF CU(NH3)2CO3

The structure and atmosphere-dependent thermochemical reactivity of di ammine copper carbonate, Cu(NH3)2CO3 has been investigated by means of combined thermoanalytical/mass spectrometric measurements, single cry stal and powder X-ray diffraction studies as well as scanning electron microscopy. It could be shown that in reducing atmosphere a series of different organic volatile species as well as Cu-degrees are formed. This observation is explained in terms of the structural vicinity of p otential volatile agents in the parent material, i.e. NH3 and CO2, as well as the in situ formation of catalytically active solid products d uring the thermochemical degradation.
