Abstract The thermal decomposition of monoclinic ammonium paratungstate (APT) and amorphous ammonium metatungstate (AMT) has been studied over the temperature range 20 to 500° C using thermogravimetry, evolved gas analysis, X-ray diffraction analysis, differential thermal analysis and scanning electron microscopy. A mechanism of decomposition which postulates the formation and subsequent decomposition of various lower ratio tungstates is proposed and substantiated by the experimental data.
