| Abstract | ||
| The substitution of barium ion (Ba2+) with lead ion (Pb2+) in the following composition: Pb10-x Bax (PO4)6(OH)2 has been investigated by an X-ray diffractometer. Samples with the range x=0 up to x=5 were calcined at 800 ºC for 25 hours, and the samples with the range from x=6 up to x=10 were calcined at 1100 ºC for 15 hours. The solid solutions hydroxyapatite samples are synthesized by the ceramic method. It was established that the sample with x=0 showed only reflections of composition Pb10(PO4)6(OH)2, while the sample with x=10 showed only reflections of composition Ba10(PO4)6(OH)2.The Samples with x = 1–9 showed more reflections called "unknown phase" besides those of pure hydroxyapatite. | ||
