Supersaturation
Definition:
(n.) The operation of supersaturating, or the state of being supersaturated.
Example Sentences:
(1) In order for a stone to form, the following conditions would seem to be necessary; transient supersaturation of the saliva in Ca++ and PO4--, a pH greater than normal, intracellular precepitation of amorphous tricalcium phosphate which is transformed into crystalline hydroxyapatite and, then, the fixation of crystals on a "matrix" such as desquamated cells, fibrils and collagens.
