A method for preparing
titanium powder relates to a method for producing
metal powder, in particular a method for preparing
titanium metal powder by using a dynamic hydrogenation
dehydrogenation process. It is characterized in that the whole process of its preparation is carried out in a furnace body with the functions of air extraction, air filling, heating and rotation. During the preparation, the furnace is heated to 450°C to start the
hydrogenation reaction in the furnace, and the furnace body is rotated so that The hydrogenated
titanium layer formed on the surface of the titanium block collides with the
steel ball and the titanium block, and is broken and separated until the hydrogenated
sponge titanium is broken into powder; the hydrogenation and crushing process is completed, stop the
rotating furnace body, and vacuumize the furnace body to make the vacuum less than 5×10-2Pa Afterwards, the temperature is raised to 600-850°C to dehydrogenate the
titanium hydride powder, and finally obtain
titanium powder. The method of the present invention directly carries out the processes of hydrogenation, crushing,
dehydrogenation and crushing continuously in the dynamic hydrogenation
dehydrogenation equipment without separating several processes independently, thereby producing high-quality and low-cost
titanium powder.
