Abstract

The invention provides a device for producing high purity titanium by a fused salt electrolysis process. The device mainly comprises a big cover (3), a crucible (5) and an anode frame (7), wherein the big cover (3) is connected with the crucible (5) by a sealed insulating pad (4) in a sealed manner; the anode frame (7) is placed in the crucible (5); a cathode (1) is arranged on the big cover (3) and connected with the big cover (3) by a sealing ring (2) in a sealed manner; and the cathode (1) is a cylinder body, the upper part of which is provided with an anode connection terminal (9). According to the device, the crucible is adopted as the anode, and the fused salt can be directly added to the crucible via a fused salt adding hole formed on the cathode; the structure of the equipment is simplified so that the production process is more stable and reliable; and the purity of the product produced by using the device can reach more than 4N5 (99.995%).

Description

technical field [0001] The invention relates to a production device of high-purity titanium, in particular to a device for producing high-purity titanium by molten salt electrolysis. Background technique [0002] In the current titanium industry, titanium with a titanium content greater than 99.995% (4N5) is called high-purity titanium, and its products can generally be divided into 4N5, 5N, 6N and other grades, mainly used for sputtering targets for VLSI . At present, the production methods of high-purity titanium mainly include: Kroll method, molten salt electrolysis method, iodide cracking purification method, electron beam melting and refining method, etc. Chlorine and titanium are produced by electrolysis of TiCl4, and high-purity titanium is also produced by electrolysis of molten salt electrolyte with low-valent titanium chloride as the main body. At present, due to the high technical requirements for the production of high-purity titanium by molten salt electrolysi...
