Title:
塩基性媒体中で電着によって得られた金属粉末をコンデショニングする方法
Document Type and Number:
Japanese Patent JP4276313
Kind Code:
B2
Abstract:
Metal powder, recovered by electrodeposition in a basic medium, is conditioned, in the absence of air, by solids/liquid separation, water washing without passivating agent addition, solids/liquid separation and vacuum evaporative drying. Conditioning of metal powder, produced by electrodeposition in a basic medium, is carried out, in the absence of air, by: (a) subjecting the powder-containing basic solution to solids/liquid separation (17); (b) subjecting the solid fraction (11) to water washing-dewatering operations (16-19), without passivating agent addition, until the wash solution (20) has the desired low pH value; (c) carrying out a further solids/liquid separation (21); and (d) subjecting the recovered wet solid fraction (18) to low temperature vacuum evaporative drying (22) until a fluid metal powder is obtained.
