GUZMAN VAZQUEZ, C.; PINA BARBA, C.  e  MUNGUIA, N.. Stoichiometric hydroxyapatite obtained by precipitation and sol gel processes. Rev. mex. fis. [online]. 2005, vol.51, n.3, pp.284-293. ISSN 0035-001X.

Three methods for obtaining hydroxiapatite (HA) are described. HA is a very interesting ceramic because of its many medical applications. The first two precipitation methods start from calcium and phosphorous compounds, whereas the third method is a sol-gel process that uses alcoxides. The products were characterized and compared. The observed differences are important for practical applications.
