The invention relates to a method for preparing carbonized titanium powder by vacuum carbothermal reduction. A method of vacuum metallurgy is adopted, and the method comprises the following steps: taking titanium dioxide and carbon as raw materials, wherein the mass ratio of the titanium dioxide to the carbon powder is 20:9-21; after crushing and briquetting, entering a vacuum furnace; heating the materials to the temperature of between 1,300 and 1,600 DEG C at a heating rate of 10-15 DEG C per minute; and keeping the temperature for 2 to 10 hours, and controlling the pressure in the furnace to between 10 and 100 Pa. Therefore, the materials undergo vacuum carbothermal reduction reaction, and ultra-fine carbonized titanium powder is prepared.
