Abstract:
1. A reactor for production of titanium-aluminium alloys, comprising: a first section having an inlet through which precursor material containing titanium subehlorides and aluminium are introduced, the first section being heatable to a first temperature at which reactions between the titanium subchlorides and aluminium occur, the first section further comprising a first moving apparatus and a gas outlet via which any gaseous by-product formed in the reactor can be removed: a second section which is heatable to a second temperature at which reactions of material transferred from the first section occur to form a titanium-aluminium based alloy, the second section further comprising a second moving apparatus; a gas driver adapted in use to cause any gaseous by-product formed in the reactions in the second section to move in a direction towards the first section; an intermediate section between the first and second sections, the intermediate section configured to be heatable to an intermediate temperature such that at least a portion of material transferred from the first section accretes on a surface of the intermediate section, the intermediate section also configured to receive gaseous by-product formed in the reactions in the second section such that the gaseous by-product is condensed in the intermediate section; and a removing apparatus for removing accreted material from the surface of the intermediate section and transferring it to the second section.
