Abstract
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.
