Factors Influencing Additive Interactions with Calcium Hydrogenphosphate

Calcium hydrogenphosphate dihydrate (DCPD) occurs in pathological mineralization. The influence of additives on its crystal growth and morphology is therefore of considerable interest. Small molecules with low charge(asparatic and glutamic acid)do not have significant effect, while small molecules with several functional groups (citrate and hexaammonium tetrapolyphosphate) adsorb on lateral faces primarily by electrostatic interactions. Molecules with hindered structure(phytate) and macromolecules (polyasparatic acid) specifically adsorb on the dominant (010) face, for which a certain degree of structural fit is necessary.
