Abstract
A process for the manufacture of substantially spherical particles of at least one metal compound of Group II of the Periodic Table, comprising dissolving such compound in a solvent therefor to form a solution and introducing the solution into a non-solvent medium; said non-solvent medium consisting essentially of at least two liquids that are non-solvents for said compound, at least one of said non-solvents being immiscible with the solvent solution and at least one of said non-solvents being miscible with said solvent solution.
