<p>Octacalcium phosphate and hydroxyapatite are provided, where octacalcium phosphate is produced as single crystals and organized polycrystalline structures that are non-dense by a process involving contemporaneous addition of calcium cation and phosphate anion to an aqueous medium at pH 4 to 7 and a temperature of 60-90 DEG C. Spherulites formed have substantially uniform blade-like crystals extending from a central nucleus, said blades being of a size in the range of about 0.1 to 5 mu . The crystals serve as fibers, which find application as e.g. coatings of prosthetic devices.</p> |
