The process research of drying UF4 by microwave

This paper make use of microwave to dry UF4 filter cake, the aim is desorbed adsorption water. The research focus on such process conditions, boat material, thickness of filter cake, drying time, setting temperature, heating power and so on. the research of desorption crystal water of UF4 that dried by microwave in fixed bed .When UF4 drying by microwave and claiming by fixed bed, the qualified UF4 powder is prepared. The research is shown that microwave can desorbs adsorption water which contain in UF4 filter cake. There is a stable water contents in UF4 after drying, and the sum of two members is less. After drying by microwave and claiming by fixed bed, the contents of water, UO2 and UO2F2 are all according to the quality standard. (authors)
