FIELD: chemistry.
SUBSTANCE: in the method, the aggregated powder is processed by stirring in a medium with a hydrogen of pH>7 to give a dispersed powder, which is then washed to a neutral pH value of the medium. Washing of the dispersed powder can be carried out with water. Washing of the dispersed powder can also be carried out with a solution of pH<7 at a temperature of 18-200°C, and then water.
EFFECT: destructiing aggregates of the powder particles and reducing their quantity, dissolving fine fraction of the sodium-thermal zirconium powder and producing coarse fraction of the zirconium powder.
