Problems solved by technology

This method has the following problems: (1) TiC X o y N z etc. as a soluble anode, the C and N elements in it will have certain pollution to the prepared high-purity titanium
(2) The preparation process of its anode still depends on high-temperature reduction conditions (up to 2000°C), and in addition, the anode preparation takes a long time (up to 600min), which cannot substantially reduce production costs
Moreover, most of the existing methods are titanium dioxide powders. To prepare blocks, titanium dioxide powders need to be sintered into blocks to prepare titanium dioxide powders. The process is complicated and takes a long time.
At present, there is no relevant research on the direct preparation of titania blocks

Abstract

The invention relates to a preparation method of a titanium oxide soluble electrode; the titanium oxide is TiO, Ti3O5, Ti4O7, Ti5O9, Ti6O11, Ti7O13, Ti8O15 or Ti9O17; the method comprises the steps of firstly, preparing the raw material into a titanium oxide block or a composite titanium oxide block formed by combining the titanium oxide with a titanium rod or a graphite rod; then, carrying out fine finishing on the titanium oxide block or the composite titanium oxide block to obtain the titanium oxide soluble electrode; a technology for preparing the titanium oxide block or the composite titanium oxide block comprises the following steps: (1) blending; (2) mixing and drying; (3) sintering by adopting a discharge plasma sintering system. The invention also provides the titanium oxide soluble electrode prepared by the method, and application of the titanium oxide soluble electrode in preparation of high-purity titanium by means of molten salt electrolysis. After the method is adopted, the titanium-containing soluble electrode which is low in contents of C and N and high in conductivity can be obtained, so that the high-purity metal titanium which is not contaminated by an anode is obtained when the titanium oxide soluble electrode is taken as the anode and / or a cathode for preparing metal titanium by means of electrolysis.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal metallurgy, and in particular relates to a titanium oxide soluble electrode, a preparation method thereof and an application in the preparation of high-purity titanium by molten salt electrolysis. Background technique [0002] Metal titanium, especially high-purity titanium, has the advantages of low density, high specific strength, good plasticity, corrosion resistance, etc., and has special memory performance and hydrogen storage performance, so it is widely used in aviation, military and atomic energy industries. High-purity titanium can also be used as a bio-substitute material in the medical field and as a target for sputtering coatings in the electronics industry, which has great potential for development. However, the bottleneck in the application of high-purity titanium lies in its difficulty in preparation. At present, the method commonly used in industry to prepare high-purity ...
