Ammonium metatungstate, referred to as AMT, is an inorganic compound with the molecular formula H28N6O41W12. It refers to a tungsten compound composed of four chemical elements: tungsten, nitrogen, hydrogen, and oxygen. It appears as a white or slightly yellow powder and is soluble in Water, insoluble in ethanol. Ammonium metatungstate has good water solubility, thermal stability, high temperature oxidation resistance, machinability, wear resistance and other characteristics. It is widely used in electronics, metallurgy, ceramics, medical, aerospace, petrochemical and other fields.
Specifically, in the field of ceramics, ammonium metatungstate is mainly used as an additive, colorant, and glaze additive in the production of ceramics and ceramic products, playing a role in improving the performance of ceramics; in the field of electronics, it is mainly used as a precursor (precursor ) is used in the production of tungsten films and can also be used as raw materials for the production of capacitors; in the metallurgical field, it can be used in the production of metal tungsten, alloy steel, ultra-fine tungsten powder, and high-specific gravity alloy tungsten powder; in the petrochemical field, it is mainly used It is used to produce tungsten-based catalysts and can also be used to prepare chemical products such as phosphotungstic acid, arsenic tungstic acid, silicotungstic acid, flame retardants, and corrosion reducers.
According to the“Ammonium Metatungstate (AMT) Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center shows that ammonium metatungstate has a wide range of application fields. With the rapid development of the downstream market, the domestic market demand for ammonium metatungstate continues to be released, and the market size shows a stable expansion trend.
At present, the main production methods of ammonium metatungstate include neutralization method, tungstic acid method, thermal decomposition method, solvent extraction method, ion exchange method, etc. Among them, the thermal decomposition method is the most competitive method for industrial production of ammonium metatungstate. It refers to using ammonium paratungstate (APT) as raw material, mixing with citric acid catalyst, thermal decomposition, adding ammonia water, evaporation concentration, crystallization, and filtration. , drying and other steps to generate ammonium metatungstate.
The main domestic ammonium metatungstate manufacturers include Jiangxi Tungsten Industry, Jiangxi Rare Earth Metal Tungsten Industry, Jiangxi Tonggu Nonferrous Metallurgy, Xiamen Tungsten Industry, Xiamen Jialu Metal Industry, Zigong Carbide, Ganzhou Haisheng Tungsten Industry, and Ganzhou Yashan Tungsten Industry, Hunan Changhong New Energy, Dayu County Weiliang Tungsten Industry, Xinfeng Huarui Tungsten and Molybdenum, etc. There are many companies and the market competition is becoming increasingly fierce. Among them, Jiangxi Tonggu is a leading enterprise in the domestic ammonium metatungstate industry. The company currently has an annual production capacity of 1,000 tons of ammonium metatungstate.
Industry analysts said that ammonium metatungstate is an important fine chemical raw material and can be used as a catalyst , raw materials, precursors, and additives are used in petrochemical, electronics, ceramics, metallurgy and other fields. Among them, ceramics and chemicals are the main application fields of ammonium metatungstate. At present, there are a large number of ammonium metatungstate manufacturers in China, and with the continuous upgrading of technology, the production capacity of local enterprises is constantly improving, and the industry development prospects are good.
