Patent ID: 8182832

Claim:
A bone replacement material comprising crystalline and X-ray amorphous phases, characterized in that a) according to 31 P-NMR measurements, said bone replacement material comprises Q 0 -groups of orthophosphate and Q 1 -groups of diphosphate, the orthophosphates or Q 0 groups making up 70 to 99.9% by weight relative to the total phosphorus content of the finished material and the diphosphates or Q 1 -groups making up 0.1 to 30% by weight relative to the total phosphorus content of the finished material, and b) according to X-ray diffractometric measurements and relative to the total weight of the finished material, 30 to 99.9% by weight of a main crystal phase consisting of Ca 2 K 1−x Na 1+x (PO 4 ) 2 where x=0.1 to 0.9, is contained in the bone replacement material and 0.1 to 20% by weight of a substance selected from the group consisting of Na 2 CaP 2 O 7 , K 2 CaP 2 O 7 , Ca 2 P 2 O 7 and mixtures thereof is contained as a secondary crystal phase.
