Dorozhkin* Kudrinskaja sq. 1-155, Moscow 123242, Russia Abstract The present overview is intended to point the readers’ attention to the important subject of calcium orthophosphates. They are of the special significance for the human beings because they represent the inorganic part of major normal (bones, teeth and antlers) and pathological (i.e., those appearing due to various diseases) calcified tissues of mammals. Therefore, the majority of the artificially prepared calcium orthophosphates of high purity appear to be well tolerated by human tissues in vivo and possess the excellent biocompatibility, osteoconductivity and bioresorbability. These biomedical properties of calcium orthophosphates are widely used to construct bone grafts. In addition, natural calcium orthophosphates are the major source of phosphorus, which are used to produce agricultural fertilizers, detergents and various phosphorus-containing chemicals. Thus, there is a great significance of calcium orthophosphates for the humankind and, here, an overview on the current knowledge on this subject is provided. Keywords: Calcium orthophosphates; Hydroxyapatite; Fluorapatite; In general, the atomic arrangement of all calcium orthophosphates Occurrence; Properties; Applications is built up around a network of orthophosphate (PO4) groups, which stabilize the entire structure. Therefore, the majority of calcium Introduction orthophosphates are sparingly soluble in water Table 1; however, all Due to the abundance in nature (as phosphate ores) and presence of them are easily soluble in acids but insoluble in alkaline solutions. -

Nelson Mandela, sometime, somewhere in South Africa Acknowledgements The work presented here was only possible due to the collaboration of different people and institutions. My first acknowledgement goes to Professor Fernando Barriga, my Ph. D supervisor. His guidance and support during the long period of this work were important to overcome the several difficulties that arose. His belief in the successful completion of this thesis and the logistic support were essential. I also acknowledge the support of Doctor Yves Fouquet in giving me the chance to develop some of the thesis studies in “Institut Français de Recherche pour l'Exploitation de la MER” (IFREMER) and for his scientific guidance. To “Fundação para a Ciência e a Tecnologia” (FCT) I am grateful for the financial support through a PhD scholarship (PRAXIS/BD/9408/96). I am also indebted to the financial support of CREMINER LARSyS and to the logistic support of “Faculdade de Ciências da Universidade de Lisboa” (FCUL). -
