What is Tungsten trioxide CAS 1314-35-8？

Tungsten trioxide CAS 1314-35-8 and blue tungsten oxide are two common tungsten oxides at present. Tungsten trioxide is also known as tungsten oxide and has the chemical formula WO3. Light yellow triclinic powder crystal. When the temperature is higher than 740°C, it transforms into an orange tetragonal crystal, and returns to its original shape after cooling. It is stable in air, with a melting point of 1473°C, a boiling point higher than 1750°C, and a relative density of 7.16. Tungsten trioxide is the most stable type of tungsten oxide. It is insoluble in water and inorganic acids except hydrofluoric acid. It can be dissolved in hot concentrated sodium hydroxide solution and ammonia water to form soluble tungstate. When the temperature is higher than 650℃, it can be reduced by H2, and at 1000~1100℃, it can be reduced by C to obtain tungsten powder.
