AbstractAbstract
[en] In the present work two methods are compared to obtain Hidroxilapatite (Ca10(PO4)6(OH)2) in a synthetic way, with similar results in their efficiency and purity. One of those methods is based on the one of H. Hayer and W. Stadlmann (1955) modified, and the other one consists of a synthesis using H3PO4, CaCl2 and NaOH. In this case two ways are presented related with the moment in which the alcalinization is carried out. Referring to the procedure of labelling, carrier free 32P is incorporated by isotopic exchange to the H3PO4, which afterwards is used in the preparation of the hidroxilapatite. (author)

En el presente trabajo se comparan dos metodos para la obtencion sintetica de Hidroxilapatita (Ca10(PO4)6(OH)2) y con resultados similares en cuanto a su rendimiento y pureza. Uno de los metodos esta basado en el de H. Hayer y W. Stadlmann (1955) modificado y el otro consiste en llegar a la sintesis utilizando PO4H3, Cl2 Ca y OHNa. En este ultimo caso se incluyen dos variantes relacionadas con el momento de efectuar la alcalinizacion. En cuanto al procedimiento de marcacion, se utilizo 32P libre de portador que se incorporo al PO4H3 por intercambio isotopico, utilizandose el 32PO4H3 asi obtenido en el proceso de sintesis.
