Abstract
On forme un mélange réactionnel contenant le sel bifluoré du métal ventilé et du sodium et/ou du potassium métallique que l'on fait réagir en présence d'un élément dopant, ce qui provoque la formation d'un gateau de fusion. La poudre de métal ventilé est obtenue par extraction de ce gateau de fusion. L'élément dopant est le soufre sous forme de soufre élémentaire et/ou de combinaisons soufrées, de préférence de combinaisons soufrées pouvant etre extraites par lavage.
