Aragonite Use In Plastics

Our data show that two amorphous precursors exist, one hydrated and one dehydrated amorphous calcium carbonate that these are formed in the tissue as 400-nm particles and that they attach to the surface of coral skeletons, remain amorphous for hours, and finally crystallize into aragonite.Since these particles are formed inside tissue.
