Abstract
Solid products of spheroidal shape and having a maximum diameter of 1 to 5,000 microns are prepared starting from a mixture of at least two immiscible, mutually chemically inert liquids, one of which is in the form of a molten solid, said liquids being prsent in the mixture in a ratio such that one forms the dispersed phase while the other is the continuous phase, at least the liquid forming the dispersed phase being one which solidifies on cooling.
