XRD analysis for immersed simulated body fluid General of (SBF) samples revealed the presence of predominant peaks corresponding to poly- Education of -Alden, crystalline Hydroxyl-apatite Ca10(PO4)6(OH)2 with hexagonal structure as well as Salah-Alden , IRAQ complete transformation of biphasic structure Na2Ca2Si3O9 and Na6Ca2P2Si3O9 phases 2 of Physics, for standard sample. Remarkably, HAp nucleation occurred within 7 days. The grain College of Science, size increased with immersion time, while the transformation of initial flake-like University of Baghdad, Na2Ca2Si3O9 structure into filamentous HAp was revealed resembling natural bone. , IRAQ Elemental analysis showed increasing Ca/P Less
