Method for reducing oxygen content of fine titanium powder

The invention belongs to the technical field of fine treatment of rare metal materials, and particularly relates to a method for reducing the oxygen content of fine titanium powder. The method comprises the following steps of (1) uniformly mixing the fine titanium powder with calcium oxide powder; (2) uniformly mixing the mixed powder obtained in the step (1) with calcium particles, and then carrying out high-temperature reaction for 0.5-4 hours; and (3) after cooling, washing the product obtained in the step (2) with dilute acid, then washing with water, and drying to obtain the low-oxygen fine titanium powder. Aiming at the problems that the fine titanium powder is easy to agglomerate or even sinter into blocks in the calcium oxygen reduction process, the using amount of calcium servingas a reducing agent is high and the like, the invention provides the method for reducing the oxygen content of the fine titanium powder, and the prepared fine titanium powder is low in oxygen content,free of agglomeration, sm
