TL;DR: The results suggest that, depending on the concentration of titanium in solution, two different mechanisms of interaction with HAp occur, and the titanium uptake by the solid seems to be primarily due to incorporation in the lattice.

TL;DR: A synthetic calcium phosphate-based biomedical material comprising gadolinium is in the form of Gd ions as mentioned in this paper, and the phase purity of the biomedical material may be at least 95%.
Abstract: A synthetic calcium phosphate based biomedical material comprises gadolinium. At least some of the gadolinium is in the form of Gd ions. The biomedical material may further comprise silicon and/or silicate. The material may comprise a compound having the general chemical formula Ca10-yGdy(PO4)6-x(SiO4)x(OH)2-x+y where 0 < x < 1.3 and 0 < y < 1.3. The phase purity of the biomedical material may be at least 95%. Also claimed is a biomedical material comprising a synthetic gadolinium-silicate co-substituted calcium phosphate based material. Also there is a process disclosed for making the biomedical materials comprising providing calcium or calcium containing compound, a gadolinium containing compound, a phosphorus containing compound and optionally a silicon containing compound and forming a precipitate by reacting the compounds in an aqueous phase at an alkali pH.
