Abstract:  The double-exchange reaction of ammonium metavanadate with calcium nitrate yielded NH4Ca(V03)3 • 4H20 and (NH4)2Ca2V10028• 17H20. The compounds have been identified by means of their infrared absorption spectra measured in the region of 400—2000 cm-1 as well as by comparison of the X-ray powder diffractograms. Their thermal decomposition was studied in the temperature range of 20 —300°C and 20—500°C by the methods of DTA and GTA.
