摘要： A process for producing titanium sponge includes carrying out a reduction reaction by supplying titanium tetrachloride to a reaction vessel which stores a reduction bath liquid containing an upper layer of a reactant bath liquid layer containing fused magnesium as a main component and a lower layer of a product bath liquid layer containing fused magnesium chloride as a main component, wherein the level of the interface between the reactant bath liquid layer and the product bath liquid layer and the level of the reduction bath liquid surface are controlled in response to an accumulated supply of titanium tetrachloride.

摘要： A process for producing metallic titanium includes forming metallic titanium fine particles by supplying liquid or mist titanium tetrachloride from above the surface of a reaction bath liquid containing fused magnesium and fused magnesium chloride in a reaction vessel to effect a reaction, wherein a circulating flow perpendicular to the bath surface of the reaction bath liquid is generated or extended just under the bath surface by imparting a stirring force to the reaction bath liquid so as to generate or increase an upward flow rate of the reaction bath liquid in at least part of the region at a depth of more than 100 mm below the bath surface.
