摘要： PROBLEM TO BE SOLVED: To provide a method for inexpensively manufacturing a titanium alloy in relation to a method for manufacturing a titanium ingot.
SOLUTION: Only chips and machining chips of titanium are used as a raw material, and the chips and machining chips of titanium are compacted into a briquette 1. When applying spot welding to a boundary line 2 between the briquettes to form an electrode, the position of the spot welding is located as follows: in addition to a central welding point 3 on the boundary line, two or more welding points are located in positions deviated from the boundary line. By increasing such welding points as above as compared with those in the case of ordinary articles, deterioration in the strength of the overall electrode can be effectively suppressed. As the result, by applying vacuum arc melting to the above electrode, the inexpensive titanium ingot can be produced with high efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing metallic titanium capable of inexpensively producing metallic titanium of high purity with satisfactory current efficiency and production efficiency, and further capable of corresponding to the serialization of production steps.
SOLUTION: A molded body or a sintered compact obtained by adding a reaction assistant to titanium oxide is reduced by electrons released at the time when active metal is dissolved in molten salt, thus metallic titanium can be rapidly and uniformly reduced to the inside of the molded body. Further, since the active metal is held to a limited region in a part of a molten salt bath, the contact of the produced metal titanium with the active metal in which impurities are concentrated does not occur. In this way, the metallic titanium of high purity can be produced.
