摘要：A process for the manufacture of substantially spherical particles of at leastone metal compound of Group II of the Periodic Table, comprising dissolving suchcompound in a solvent therefor to form a solution and introducing the solution into anon-solvent medium; said non-solvent medium consisting essentially of at least twoliquids that are non- solvents for said compound, at least one of said non-solvents beingimmiscible with the solvent solution and at least one of said non- solvents being misciblewith said solvent solution.
