| titleOfInvention | Method for regenerating tungsten carbide and tungsten-based materials |
| abstract | Tungsten carbide and / or tungsten can be regenerated by oxidizing the tungsten composition at a temperature of 700 ° C or higher to form water-insoluble tungsten trioxide. Which is then reduced to form tungsten dioxide. Tungsten dioxide is applied to low temperature oxidation to form monoclinic tungsten trioxide. The monoclinic tungsten trioxide is then dissolved in ammonia to form ammonium tungstate. Converts a binder metal such as cobalt, which may be present, into a soluble amine complex. It is spray dried and carbonized to form tungsten carbide. If the formed composition comprises cobalt or other binder metal, the ratio of cobalt to tungsten may be adjusted by adding the cobalt salt or ammonium metatungstate to the aqueous solution prior to spray drying to form the precursor composition. Which is uniquely suited for forming cobalt tungsten carbide compositions. |
