45S5 Bioglass-Derived Glass-Ceramic Scaffolds Containing Niobium Obtained by Ge...
Siqueira,Lilian de; Grenho,Liliana; Fernandes,Maria H.; Monteiro,Fernando J.; Trichês,Eliandra S.Scaffolds of bioglass derived from BG45S5 (45 wt% SiO2, 24.5 wt% CaO, 24.5 wt% Na2O and 6 wt% P2O5) containing 10 wt% niobium were prepared by gelcasting method. The scaffolds presented a 3D porous structure with interconnected and spherical pores (pore size range 100 μm to 500 μm) and high porosity (89%), similar to trabecular architecture of spongy bone. The compressive strength was 0.18 ± 0.03 MPa which is a...
