Abstract:
A biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material having a sintered CAP core and at least one closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core, whereby the epitactically grown nanocrystals have the same size and morphology as human bone mineral, wherein the closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core has a non-homogeneous external surface comprising individual clusters of flat crystal platelets consisting of epitactically grown HAP nanocrystals and coarse areas between the individual clusters, whereby the percentage of the coarse areas between the individual clusters as measured by SEM is at least 20% of the total surface, which material shows an increased capacity to induce bone formation, and a process of preparation thereof.

Claim (Index 14):
The process of  claim 12 , wherein washing the separated solid material involves 2 to 10 washing steps with pure water directly followed by at least one washing step with a short-chain aliphatic alcohol.
