The investigation of thermal decomposition mechanism of ammonium phosphotungstate hydrate in inert gas atmosphere

Abstract

In this study. TGA-DTA-MS and TGT techniques were used to investigate the thermal decomposition of ammonium phosphotungstate hydrate ((NH4)(3)(PW12O40)center dot xH(2)O, APhT) in inert gas (Ar) atmosphere. The thermal decomposition products of APhT obtained in Ar atmosphere at various temperatures were characterized by using XRD, FT-IR and SEM analyses.
