Latest Patents
One of his latest patents is a process for the production of crystalline titanium powder. This invention provides a method for producing crystalline titanium powder containing single crystals or agglomerates of single crystals with an average crystal size greater than 1 µm. The process involves reacting a titanium chloride species, preferably titanium dichloride, with a reducing metal in a continuous back-mix reactor. This innovative approach results in a free-flowing suspension of titanium powder in molten chloride salt.
Another significant patent by Van Vuuren is related to the upgrading of titaniferous material. This method includes nitriding and reducing a titaniferous material that contains TiO and Fe oxides in the presence of nitrogen and carbon. The process converts TiO to TiN while reducing most of the Fe oxides to Fe. The Fe is oxidized preferentially to TiN, allowing for the removal of Fe ions and producing an upgraded low-Fe TiN bearing material.
