Title:
METHOD FOR PRODUCING TITANIUM METAL
Document Type and Number:
WIPO Patent Application WO/2010/137688
Kind Code:
A1
Abstract:
Disclosed is a method for producing titanium metal, which comprises: (a) a step in which a mixed gas is formed by supplying titanium tetrachloride and magnesium into a mixing space that is held at an absolute pressure of 50-500 kPa and at a temperature not less than 1700˚C; (b) a step in which the mixed gas is introduced into a deposition space; (c) a step in which titanium metal is deposited and grown on a substrate for deposition; and (d) a step in which the mixed gas after the step (c) is discharged. In this connection, the deposition space has an absolute pressure of 50-500 kPa, the substrate for deposition is arranged in the deposition space, and at least a part of the substrate for deposition is held within the temperature range of 715-1500˚C.
