<b><i>In‐vitro</i></b> preparation of nanocrystalline calcium phosphates as bone substitution materials in surgery

Abstract

Abstract A continuous preparation method for nanoscopic calcium phosphate ceramics is presented. The influence of processing parameters (temperature, time) on the properties of calcium phosphates was studied. Crystallinity, structure, and morphology are important for an application as biodegradable implant material in bone contact. The samples were studied in detail using X‐ray powder diffraction, infrared spectroscopy, atomic absorption spectroscopy, photometry, scanning electron microscopy, and transmission electron microscopy. All calcium phosphate precipitates are non‐stoichiometric, calcium‐deficient hydroxyapatites.
