Dispersions of a finely-divided alkali metal, with practically uniform particle size and uniform alkali metal concentration, are prepared continuously by dispersing a molten alkali metal in an inert organic diluent by means of a dispersant which is soluble in the diluent and also, if necessary, a stabiliser, by subjecting the molten metal to great shearing force, so as to form metal particles which are smaller and greater than a predetermined particle size, allowing particles of this predetermined size or larger to settle, and separating finer particles with a size up to the predetermined size, continuously recycling the coarse particles to the shearing zone, and repeating the process, with continuous addition of molten alkali metal and withdrawal only of alkali metal particles with a size corresponding to or less than the predetermined particle size.
