“…12) we observe different silicocarnotite aggregates, which are composed of the glass-ceramic particles embedded in gelatine matrix [17]. As described in reference [12] SEM image also depicts the presence of hollow zones with various pore diameters (5 and 6.7 μm) and we also see that the silicocarnotite preserves its morphology in the conditions used. In accordance with our previous investigation [36], silicocarnotite thermally treated at 1200 o C/2 h could be ascribed as an non-densified sample.…”

Abstract:In this work we present our experimental results on synthesis, structure evolution and in vitro bioactivity assessment of new gelatin/ silicocarnotite hybrid materials. The hybrids were obtained by diluting gelatin (G) and silicocarnotite (S) ceramic powder with G:S ratios of 75:25 and 25:75 wt.% in hot (40 o C) water. The hybrids were characterized using XRD, FTIR, SEM/EDS and XPS. FTIR depicts that the "red shift" of amide I and COO -could be attributed to the fact that the gelatin prefers to chelate Ca 2+ from S. The growth of calcium phosphates on the surface of the hybrids synthesized and then immersed in 1.5 SBF for 3 days was studied by using of FTIR, XRD and SEM/EDS. According to FTIR results, after an immersion of 3 days, A and B-type CO 3 HA can be observed on the surface. XRD results indicate the presence of hydroxyapatite with well defined crystallinity. SEM/EDS of the precipitated layers show the presence of CO 3 HA and amorphous calcium phosphate on the surface of samples with different G/S content when immersed in 1.5 SBF. XPS of the G/S hybrid with 25:75 wt.% proved the presence of Ca-deficient hydroxyapatite after an in vitro test for 3 days. Warsaw and Springer-Verlag Berlin Heidelberg. © Versita
