The thermal decomposition of monohydrated ammonium oxotris (oxalate) niobate
The thermal decomposition in argon of the monohydrated ammonium tris(oxalate)niobate, (NH4)3NbO(C2O4)3.H 2O, has been studied by TG/DTG, DTA, DSC, IR absorption and XRD. The material decomposes stepwise by the release of CO, CO2, NH3 and water. The atomic structure of the complex initially becomes a...
