Abstract

Изобретение относится к применению соединения формулы KMgFдля улавливания металлов, присутствующих в форме фторидов и/или оксифторидов в газовой или жидкой фазе. Изобретение также относится к соединению формулы KMgF, обладающему удельной площадью поверхности, по меньшей мере, равной 30 м/г и самое большее равной 150 м/г, а также к способам его получения. В значительной мере изобретение применимо в ядерной промышленности, где оно может быть с успехом применено для очистки гексафторида урана (UF), присутствующего в газообразном или жидком потоке, от примесей металлов, которые также присутствуют в этом потоке.
