A method of preparation of ultrafine CaCO3 particles in ordered systems, as in vesicle and microemulsion, consisting of egg yolk phospholipid and water has been introduced. The size of CaCO3 grain was controlled by the content of egg yolk phospholipid and size of liposoms in the systems. It was found by experiment that vaterite is formed inside the doublle layer vesicles but calcite is formed outside of the vesicles. A discussed of the cause of this difference has been given.
