Synthesis of WF6 by Fluorination of Tungsten Metal with Flowing Fluorine in a Fixed Bed Tungsten Reactor

Based on a physicochemical model of the fluorination of tungsten metal fluorine, we derived an equation for calculating the completeness of the use of fluorine depending on the dimensions of the reaction surface, fluorine feed as well as the temperature and the activity of the tungsten surface, which determine the value. The process of WF6 synthesis based on two-fold iteration’ the fluorination of tungsten – WF6 condensation’, which provides the performance of 5.22 kg/hour WF6, the completeness of the use of fluorine >99.99% and the emission of harmful gases within maximum permissible concentration.
