Abstract

Biological calcium phosphates are, with few exceptions, poorly or partly crystalline and impure, and sometimes comprise a mixture of phases. Each component of a complex calcified deposit may be described with reference to some highly crystalline model compound of perfect stoichiometry such as the minerals hydroxyapatite (HAP, Ca10(OH)2(PO4)6), brushite (DCPD, CaHPO4·2H2O) and monetite (DCPA, CaHPO4), or octacal-cium phosphate (OCP, Ca8H2(PO4)6· 5H2O). The fascination of biological calcium phosphates arises from the deviations from these well-defined forms resulting in unique physical and chemical properties, some of which may reflect the history of the structure. Thus, the degree of static and dynamic disorder, the nature and location of substituents in a lattice, and larger-scale morphological differences such as crystal size, interlayering with non-calcium phosphate phases and crystal orientation, have all to be described. Infrared spectroscopy can and has played a part in the characterisation of biological calcium phosphates. Fourier transform instruments can do better what was done before and make possible some new types of measurements.
