Graphite Boat And Method For Producing Tungsten Carbide By Direct Carbonization of WO3+C+H2 Using Same

Brief description of this technology:
The invention discloses a graphite boat and a method for producing tungsten carbide by directly carbonizing WO3+C+H2 with the graphite boat, where the graphite boat is combined of top and bottom cabins, and the method: putting WO3 and C mixed powders into the two cabins, and directly producing WC in a carbonization furnace ventilated by hydrogen gas.

                
The invention can obtain WC product with uniform size, and stable carbon content; can shorten the whole reaction time of WO3 with C and H2, increasing WC output; can reduce H2 utilization, saving production cost; and can prolong service life of the carbonization furnace.
