TY - JOUR AU - Rokhmistrov, D. AB - Calcium phosphate was prepared by aqueous wet‐chemical precipitation from sodium phosphate and calcium nitrate under standard conditions. By incomplete removal of the mother liquor, the by‐product sodium nitrate remained in the dried powder. Upon annealing at 1150°C, the sodium‐rich phases β‐rhenanite (NaCaPO4) and Na3Ca6(PO4)5 were formed. If the powder was first compacted and then annealed at 1150°C, the sodium‐rich phases were enriched in the sample surface up to a depth of about 140 μm as shown by X‐ray powder diffraction. As these phases have a higher water solubility than sintered hydroxyapatite, they will enhance the resorption of such a ceramic in contact with hard tissues.
