The method of using optimal promoter development for the reduction-carburization of WO3 by using carbon monooxide

摘要

The present invention is the reduction of oxidized tungsten-carbide relates to a method of improving process efficiency; ; in the oxidation-reduction tungsten-carbide using the carbon monoxide in the process according to the process for producing a tungsten carbide, silica, in the process, alumina, mixed material similar physical properties as the agent for improving the efficiency of the reaction, such as zeolite carried out at a temperature of 300 to 800 degrees Celsius, and further tungsten carbide which is prepared by the process by the use of the efficiency-improving agent, and its particle distribution is 40 to 400 nm, the tungsten oxide instead Similar recognition properties of Ta, Ti, Si makes it possible to use an oxide of producing a carbonated Ta, carbide Ti, Si carbide or metal Ta, metal Ti, metal Si; ; prices of zeolite, alumina, reduced by the addition of silica gel using carbon monoxide carbide By forming the step, increasing the reaction efficiency and to reduce the size of the particles makes it possible to manufacture a high-quality carbonized tungsten as a lower cost by improving the physical properties.
