Hydroxyapatite (HAP) is a conflicting material: On the one hand, HAP is greatly available in nature as bone or tooth mineral material, but, on the other hand, these natural samples only hardly fulfill the needs of science concerning chemical composition or structural simplicity. Therefore and because the material has important influence in physiology, this study aims for a preparation method for artificial HAP samples of high density. In order to make available the basic interactions, best possible homogeneity and chemical purity is achieved as well as structural smoothness. A thorough characterization of the samples is presented together with some results of an investigation of the effects of fluoridation.
