Abstract: It is an object of the present invention to provide a method of manufacturing titanium hydride powder that is capable of manufacturing titanium hydride by using titanium scrap generated during machining as a raw material. Further, according to the method of manufacturing titanium hydride powder, since the titanium scrap is hydrogenated and changed into powder at the same time for a short time, it is possible to reduce the number of processes and manufacturing cost and to improve productivity. In order to achieve the object, according to an embodiment of the present invention, a method of manufacturing titanium hydride powder includes charging titanium scrap into a reaction container, removing air in the reaction container and supplying hydrogen gas to the reaction container, and performing ball milling.
