METHOD FOR MAKING DISPERSED METALLIC POWDER Russian patent published in 1995 - IPC

Abstract RU 2030972 C1

FIELD: powder metallurgy. SUBSTANCE: first water solution of alkali is prepared. Then metallic salt is treated with this solution to extract hydroxide of corresponding metal. Extracted metallic hydroxide is filtered and washed. These operations are combined with the milling of extracted material. Further metallic hydroxide is dried and after that recovered to a metal. For this purpose hydrogen is passed through extracted material during its heating to a temperature exceeding the threshold of recovery of metallic hydroxide. EFFECT: enhanced quality. 6 cl
