- Abstract
- The feasibility of producing nano-sized WC and WC-Co powders by reduction and carburization of WO3 and Co3O4 under hydrogen and methane atmospheres was evaluated, WC powders of 1 mum in particle size were obtained from WO3 on reduction and carburization at 950 degreesC. On the other hand, nano-sized WC-Co powders with a particle size of similar to 100 nm could be produced by a two-step reduction process, using a blend Of WO3 and Co3O4. Critical control parameters in this process, such as the gas flow rate, temperature and treatment time, were found.
