APPARATUS AND METHODS FOR THE PRODUCTION OF METAL COMPOUNDS

摘要

The present invention relates to a stepwise method for the production of titanium-aluminium compounds and some titanium alloys and titanium-aluminium inter-metallic compounds and alloys. In a first step an amount of aluminium is mixed with an amount of aluminium chloride (AlCl3) and then an amount of titanium chloride (TiCl4) is added to the mixture. The mixture is heated to a temperature of less than 220 ‹C to form a product of TiCl3, aluminium and AlCl3. In a second step, more aluminium can be added if required, and the mixture heated again to a temperature above 900 ‹C to form titanium-aluminium compounds. This method results in the production of powdered forms of titanium-aluminium compounds with controllable composition. Suitable reactor apparatus is also described. ® KIPO & WIPO 2009
