Abstract
The present invention relates to a material with orthophosphate and having a high solubility which can be used as a bioactive bone replacement material and as a substrate material in biotechnology. According toP-NMR measurements, the new material comprises Q-groups of orthophosphate and Q-groups of diphosphate, the orthophosphates or Q-groups making up 65 to 99.9% by weight relative to the total phosphorus content of the finished material and the diphosphates or Q-groups making up 0.1 to 35% by weight relative to the total phosphorus content of the finished material, and wherein according to X-ray diffractometric measurements and relative to the total weight of the finished material, 35 to 99.9% by weight of a main crystal phase consisting of CaNa(PO), CaK(PO), mixtures thereof or mixed crystals according to the general formula CaKNa(PO), where x=0 to 1, is contained in the bone replacement material and 0.1 to 25% by weight of a substance selected from the group consisting of NaCaPO, KCaPO, CaPOand mixtures thereof is contained as a secondary crystal phase, and the X-ray amorphous phases contained besides the main crystal phase jointly make up 0.1 to 65% by weight.
