ABSTRACT:
The invention relates to a hydroxylapatite material containing phosphate wherein the microporous structure of algae hard-tissue raw material is retained in the end product and which can be obtained by reacting an organic compound devoid of algae hard-tissue in an alkaline aqueous phosphate solution by adding magnesium ions at an elevated temperature. The invention also relates to a method for the production of said hydroxylapatite material containing tricalcium phosphate, which is characterized in that it is especially well resorbed in the body, is especially suitable as a bone substitute material or as a carrier material for active ingredients. Said material can also be used as a filter material.
