Resumen

PEON, E. et al. Preparation and characterization of porous blocks of synthetic hydroxyapatite. Lat. Am. appl. res. [online]. 2004, vol.34, n.4, pp. 225-228. ISSN 0327-0793.

Porous structures were conformed by pressing and heating of hydroxyapatite powders. Samples were obtained in the form of blocks with 47 % porosity. An interval of pore sizes interconnected among 50-120 mm was obtained. The diametrile tensile stress of evaluated samples oscillated between 4 and 21 MPa, according to what has been reported for porous ceramics. The diffraction studies of x-ray of heated samples indicated an increase of hydroxyapatite crystallinity. The microstructure was studied by scanning electronic microscopy. Statistical techniques were employed to determine the certainty of the answer.
