Abstract: A manufacturing method of a tungsten-yttria rod is provided to produce a tungsten-yttria rod improved in heat-proof and ablation resistance by warm-extruding a sintered body. A manufacturing method of a tungsten-yttria rod comprises the steps of: forming a powder molded body by compression-molding compound powder consisting of tungsten powder 95~99.5 weight% and yttria powder 0.5~5 weight(S11); reducing a surface oxide layer of the powder molded body by increasing the surrounding temperature to 800°C; removing metallic impurities from the powder molded body by increasing the surrounding temperature to 1900°C; sintering the powder molded body for a fixed time to form a sintered body by increasing the surrounding temperature to 2000~2500°C at increasing rate lower than that in the above reducing and removing steps(S12); a step of removing the residual hydrogen inside the sintered body by decreasing the surrounding temperature to 1200°C; warm-extruding the sintered body to form an extruded body with enhanced strength and density(S13); and heat-treating the extruded body at the temperature of 1000~1300°C for half an hour or an hour so that the residual stress of the extruded body is removed.
