Engineering computational method of process of fluorination metal tungsten

Abstract

In this paper, we consider the process of obtaining the tungsten hexafluoride gas. On the basis of a simple one-component diffusion model of the process of fluorination of tungsten metal recorded an equation relating the rate of a chemical reaction and change in concentration of a key component of the length of the reaction zone. The numerical calculations showed good agreement with experimental data. The statistical treatment of experimental data, constructed regression model for the reaction speed parameter fluoridation as a function that depends on the temperature of the supplied gas and tungsten metal particle size. The results can be used to optimize the design of existing devices and new designs for the fluorination process of metal tungsten.
