METHOD OF PRODUCING DISPERSED LITHIUM AND LITHIUM-BASE ALLOYS Russian patent published in 1999 - IPC

FIELD: methods of production of dispersed lithium and lithium-base alloys. SUBSTANCE: method includes loading of initial material and thermoplastic fluid, heating of initial material and thermoplastic fluid up to melting, dispersion by agitation with flow of thermoplastic fluid under conditions of turbulent flow in atmosphere of inert gas with excessive pressure maintained above melt, and cooling with vacuum treatment and maintenance of residual pressure. Initial material and thermoplastic fluid are loaded in ratio of 1: (1-5). Thermoplastic fluid is used in the form of mineral oil or paraffin. Initial material and thermoplastic fluid are heated up to temperature of 210-240 C. Dispersion by agitation is carried out with cooling of melt to temperature of 180-190 C. Inert gas is used in the form of argon. The method allows production of lithium granules and granules of lithium-base alloys in the form suitable for further operation and yield of granules of preset fraction composition. EFFECT: higher efficiency. 9 cl, 2 dwg
