Tungsten: Properties, Production, Applications & Alloys
Once tungsten ore has been processed and separated, the chemical form, ammonium paratungstate (APT), is produced. APT can be heated with hydrogen to form tungsten oxide or will react with carbon at temperatures above 1925°F (1050°C) to produce tungsten metal.
Tungsten is considered to be a conflict mineral due to the unethical mining practices observed in the Democratic Republic of the Congo. There is a large deposit of tungsten ore on the edge of Dartmoor in the United Kingdom, which was exploited during World War I and World War II as the Hemerdon Mine.
Tungsten Statistics and Information
Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides. Cemented carbides (also called hardmetals) are wear-resistant materials used by the metalworking, mining, and construction industries. Tungsten metal wires, electrodes, and/or contacts are used in lighting, electronic, electrical, heating, and welding
