Appearance : White crystalline powder or yellow powder.

Boiling point Decomposes at 600 °C

Solubility : slightly soluble in water, while 20 ℃ solubility less than 2% in water, insoluble in alcohol. The Ammonium paratungstate will lose some ammonia and water of crystallization when heated to 220-280 ℃, can be converted as ammonium metatungstate. Will lose all crystal water and ammonia when heated to above 600 ℃, into completely yellow tungsten oxide.
