A severe control of carbon content is needed for the direct production of WC from WO3. In order to solve this problem for an industrial scale, a rotary carburization furnace for high temperatures was developed. This furnace comprises a rod-shaped heater of graphite in the center of the furnace and a rotating cylinder of graphite positioned coaxially around this heater. The inner wall of rotating cylinder is heated indirectly by means of supplying electric power to the graphite heater.<BR>The mixed powder of WO3 and carbon was granulated and the resulting granules were continuously fed into the furnace which was kept at 1150°C-1650°C.<BR>WO3 was sufficiently reduced and carburized by carbon in this furnace. The gases formed during reaction in the rotary furnace were CO and CO2, and the ratio PCO2/PCO corresponded to the carbon content of the carburized product.<BR>It became clear from these results that the carbon content can be controlled by the ratio PCO2/PCO which is subject to the operating conditions of the rotary furnace.
