Rapid resorbable, glassy crystalline materials on the basis of calcium alkali orthophosphates

Materials based on calcium orthophosphates have been developed to crystallize spontaneously and directly from the melt. The main crystalline phase consists of a new synthesized chemical of formula Ca2KNa(PO4)2. This compound crystallizes in a very wide range of chemical compositions as shown. Furthermore, the solubility was tested and compared with that of self-prepared α-tricalcium phosphate ceramics and commercial products of hydroxyapatite ceramics and surface-modified α-tricalcium phosphate ceramics. The results show that new materials containing the compound Ca2KNa(PO4)2 had the highest solubility in comparison with other tested materials.
