Abstract
The paper carried out approbation of dry fluoride technology for processing of zirconium-containing raw materials and treatment of the resulting fluorides from impurities under semi-industrial conditions. Research results of the process of fluorination of zircon and baddeleyite with elemental fluorine in devices of periodic and continuous action were given. The feasibility of efficient treatment of zirconium tetrafluoride from impurities via vacuum sublimation was demonstrated. Thus, high purity zirconium tetrafluoride was obtained. The design of a sublimation apparatus manufactured and tested under operating production conditions was proposed.
