Epitaxy as a Growth Factor in Urinary Calculi and Gallstones

EPITAXY 1 consists of the growth of one crystal, in one or more particular orientations, on a substrate of another, with a near geometrical fit between the respective networks which are in contact. Thus anthraquinone can grow on rocksalt 2 and d - or l -camphor on d - or l -quartz 3 . That there is...

Description
Summary:EPITAXY 1 consists of the growth of one crystal, in one or more particular orientations, on a substrate of another, with a near geometrical fit between the respective networks which are in contact. Thus anthraquinone can grow on rocksalt 2 and d - or l -camphor on d - or l -quartz 3 . That there is some influence of the structures themselves (apart from the geometry) has been proved, but it is of surprisingly minor importance 3 . There is also a dependence of the degree of misfit which can be tolerated on the degree of supersaturation of the solution from which the epitaxial crystals are deposited 4 .
