The effects of Na4P2O7.10H2O addition on the mechanical properties of sintered Ca2P2O7 bioceramic

摘要: Abstract From the viewpoint of hard tissue response to implant materials, calcium phosphates are probably most compatible materials presently known. Thus, during last few years much attention has been paid hydroxyapatite and β-tricalcium phosphate as potential biomaterials for bone substitute. However, disadvantage all proposed ceramics is their low mechanical strength. Therefore, applicability these restricted non-stressed regions. The ultimate good implantation in skeleton reach full integration non-living with living bone. material could be used, a graft, itself resorbs or dissolves growth occurs, end result new remolded Ca 2 P O 7 one intermediate products mineralized crystal from amorphous phosphates. doped certain amount Na 4 · 10H was prepared developed material. In this study, used liquid phase sintering additive which expected improve process promote physiological bioresorbability. Compressive strength four-point bending were measured by Bionix 858 test system. At beginning, proportionally increased addition up 5 wt.%, but thereafter decreased. microstructure crystalline identification analyzed techniques scanning electron microscopy (SEM), probe micro-analysis (EPMA), transmission (TEM) X-ray diffraction (XRD). relationship between sintered bioceramics dopant given terms presence NaCa(PO 3 ) , grain abnormal coalescence while increased.
