Product Code : AL-APT-CU
Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.
Ammonium paratungstate (APT) is a white crystalline salt with the chemical formula (NH4)10(H2W12O42)·4H2O. It is described as "the most important raw material for all other tungsten products." When ammonium para tungstate is heated to between 220 and 280 degrees Celsius, it loses part of its ammonium and water compounds, transforming into ammonium metatungstate. This new compound is a highly pure, water-soluble tungsten powder that is almost completely free of alkali and metallic impurities.
ATT is a professional supplier of Ammonium Paratungstate (APT), We also produce disc, granules, ingot, pellets, pieces, powder, rod, wire, sputtering target and in numerous other forms and custom shapes. Other shapes are available by request.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.
