Document Type and Number:
WIPO Patent Application WO/2018/179993
Kind Code:
A1
Abstract:
Titanium sponge manufactured by the Kroll process, the titanium sponge characterized in that the total of the chlorine content and the magnesium content therein is 350 mass ppm and the bulk density thereof is 1.65-1.95 g/cm3. Through the present invention, it is possible to provide titanium sponge for manufacturing of a large-sized ingot in which the composition thereof can easily be controlled and problems due to chloride inclusion during smelting of a large-sized ingot by a melting method not involving compression molding do not readily occur, and a method for manufacturing the titanium sponge with high industrial efficiency.
