Abstract: PURPOSE: A method of manufacturing low-oxygen titanium powder is provided to manufacture low-oxygen titanium powder since deoxidation is done below a melting point of calcium, so the content of oxygen is low relative to titanium powder manufactured. CONSTITUTION: A method of manufacturing low-oxygen titanium powder comprises next steps. In a deoxidation container, titanium raw-powder of 100weight% is arranged, calcium of 50-200weight% is arranged on the lower part of the titanium raw-powder(S110). The deoxidation container is heated at 850~1050°C, and the calcium is evaporated and makes the titanium raw-powder to deoxidize the titanium raw-powder(S120). The deoxidized titanium powder is washed, calcium oxide is removed from the surface of the deoxidized titanium powder(S130). The titanium powder without the calcium oxide is dried(S140).
