In industrial applications, ammonium metatungstate is mainly used to manufacture tungsten compounds such as tungsten oxide and ammonium phosphotungstate, and is also used as a catalyst for petrochemical industry and a colorant for ceramics. In petroleum industry, catalysts containing ammonium metatungstate have excellent catalytic activity, good selectivity and excellent water solubility. In the ceramic industry, it can be used as a colorant or mineralizer to influence the tone and color level of ceramic products by adjusting the amount of addition in the formula.
