  • Method for producing tungsten carbide
    Publication number: 20020009411
    Abstract: A method for the production of fine-grain tungsten carbide (WC) powder comprising heating a tungsten precursor compound in contact with a gas mixture including a hydrocarbon such as methane (CH4). The method is preferably a one-step continuous method wherein the heating rate and reaction temperature is well controlled for the economical production of high quality tungsten carbide powder. The tungsten carbide powder advantageously has a high purity and a small crystallite size and can be used in the manufacture of products such as cutting tools having high wear resistance.
