Tungsten carbide is manufactured by direct carburization of tungsten with carbon, or Tungsten is converted back to the ammonium para-tungstate (APT) form, an early point in the tungsten carbide manufacturing process.
Tungsten carbide is a grey-black powder that can be pressed and made into shapes through sintering. It is two times as stiff as steel, and has double the density of steel. It is commonly used in drilling, sports equipment and jewelry.
Tungsten carbide is a chemical compound that contains equal parts of tungsten and carbon atoms. It is the most important tungsten compound as it is noted for its strength.
Tungsten carbide powder has many applications, including:
