Abstract
Master alloys of lithium or other alkali metal with a second metal such as alumium are made by exposing mechanically aloyed powder of the second metal to molten alkali metal. The exposure can be in an inert liquid medium such as a high boiling point hydrocarbon or in a dry, inert gas medium. In order that contact between the lithium and the second metal be efficient, significant, shear inducing agitation is required when the process is carried out in a liquid medium and kneading action, either manual or mechanical is required when the process is carried out dry in an inert gas medium.
