Usual analytical techniques (X-ray diffractionanalysis, Fourier transformed infrared spectroscopy, Thermo gravimetric analysis, Scanning electronmicroscopy, X-ray dispersive energy analysis and Porosimetry) were employed to characterize the resultingmaterial. The aim of this investigation was to study the bioceramic properties of the pastes with nondecayingbehavior from chitosan-hydroxyapatite composites. Chitosan, which also forms a water-insolublegel in the presence of calcium ions, and has been reported to have pharmacologically beneficial effects onosteoconductivity, was added to the solid phase of the hydroxyapatite powder. The properties exhibitedby the chitosan-hydroxyapatite composites were characteristic of bioceramics applied as bone substitutes.Hydroxyapatite contents ranging from 85 to 98% (w/w) resulted in suitable bioceramic composites for boneregeneration, since they showed a non-decaying behavior, good mechanical properties and suitable pore sizes. 2001 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32773406 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.73 |
