Ammonium paratungstate is a relatively stable compound, but it will decompose under certain conditions. For example, under strong acidic conditions, ammonium paratungstate will undergo hydrolysis and decomposition reaction to produce volatile tungstate and ammonia gas. In addition, when exposed to air at high temperature or for a long time, ammonium paratungstate may also undergo decomposition reaction and lose volatile tungsten oxide compounds. Therefore, in order to maintain its stability, ammonium paratungstate should be stored in a dry, light-proof and sealed container to avoid the impact of acidity and high temperature.
