Abstract
A method (500) for producing a titanium product is disclosed. The method (500) can include obtaining TiO2-slag (501) and reducing impurities in the TiO2-slag (502) to form purified TiO2 (503). The method (500) can also include reducing the purified TiO2 using a metallic reducing agent (504) to form a hydrogenated titanium product comprising TiH2 (505). The hydrogenated titanium product can be dehydrogenated (506) to form a titanium product (508). The titanium product can also be optionally deoxygenated (507) to reduce oxygen content.
Claims29
A method for producing a titanium product, comprising:
- obtaining TiO2 rich material as a purified TiO2 having at least 70% by weight TiO2;
- reducing the purified TiO2 by combining with a metallic reducing agent and a molten salt at a temperature and a pressure to produce a hydrogenated titanium powder product comprising TiH2 and optionally elemental titanium;
- heat treating the hydrogenated titanium powder product under a hydrogen atmosphere to coarsen the powder so as to reduce pore size and specific surface area to form a heat treated hydrogenated titanium powder product, wherein the hydrogen atmosphere is maintained during at least one of heating and cooling;
- and
- deoxygenating the heat treated hydrogenated titanium powder product to reduce residual oxygen to less than 0.2 wt % to form a deoxygenated hydrogenated titanium powder product.
