Obtaining sorption materials based on alkali and alkaline-earth metal fluorides for separation of the azeotropic mixture UF6–HF

  • A. A. Fiskov
  • A. Yu. Makaseev

Methods of obtaining granular sorbents for catching and purifying volatile inorganic fluorides are examined. The results of optimizing the technology of granular lithium fluoride and approaches to obtaining pelleted barium and calcium fluorides are presented. The granules obtained gave capacity to 0.6 g HF/g sorbent while maintaining the initial structure. The initial destruction was negligible, the number of destroyed granules was the same after three sorption-desorption cycles.
