| dc.description.abstract | Porous silicate glass monoliths were obtained from two inexpensive precursors; sodium metasilicate (waterglass) (Na2SiO3) (SMS) and bentonite clay (BTC) using the sol gel synthesis. The optimal gelation mole ratio for SMS was (Na2SiO3 : H2O : H2SO4 : C2H5OH) of (1 : 13.54 : 0.5 : 1.68); while gelation for BTC was (BTC : H2O : H2SO4 : C2H5OH) of (1 : 13.54 : 1.0 : 1.68). The gels obtained were initially washed with deionised water to free the (Si-O-Si) framework from Na2SO4 as by-product of the hydrolysis, followed by aging, drying at low temperature before finally sintering at 600°C to give the monoliths. The bulk density of the monoliths obtained were determined, and further characterized using Fourier transform infra red (FTIR) spectroscopy, X-ray diffraction (XRD) spectroscopy, Atomic absorption spectroscopy (AAS), and Scanning electron microscopy (SEM). The monoliths show macroporous structure with pore size ranging from 150 – 250 nm, and can be further tailored to give scaffolds for bone tissue repair. | en_US |
