Title: Method for producing high melting point metal
Inventor: KOBAYASHI KEIICHI
IPC: C22B34/12
Filed: 2013-04-26
Abstract: PROBLEM TO BE SOLVED: To efficiently and securely solve the problem of iron contamination caused by the iron lining of a reaction vessel without exerting an adverse effect on an original operation in the production of sponge titanium by a Kroll process.SOLUTION: Magnesium and magnesium chloride remaining in sponge titanium after a reduction reaction step are removed by a vacuum separation step. Since their removal regenerates insufficient high chlorine sponge titanium, the high chlorine sponge titanium is made into granulated grains 10, and again, vacuum separation treatment is performed. In the reseparation step, a produced unused reaction container 20 is used. The remaining magnesium and by-produced magnesium chloride are removed from the granulated grains 10, and further, an alloy layer of iron and titanium by solid phase diffusion reaction is formed at the inside face of the container with which the granulated grains 10 are contacted. By the formation of the alloy layer, iron elution when the reaction container is used for the reduction reaction step is suppressed.
