METHOD TO PRODUCE DEAGGLOMERATED AND DEAGGREGATED POWDER MATERIAL Russian patent published in 2011 - IPC G21C3/62

Abstract RU 2417463 C2

FIELD: power engineering.

SUBSTANCE: method to produce at least one deagglomerated and deaggregated powder material - method includes the following serial stages: (a) introduction of at least two powders into a vibration mill, when each powder contains UO₂ with close specific surfaces, produced by various synthetic methods, and (b) shaking powders in the mill to form deagglomerated and deaggregated powder material, with intensity of grinding, sufficient so that the specified powder material consists of crystallites only.

EFFECT: provision of process to produce powder material having same sintering ability independently on condition of agglomeration and aggregation of initial powders, and having sintering ability characterised by extremely low dependence on density of non-sintered pressed stocks.
