Fe-containing nominal wollastonite (CaSiO3)–Na2O glass-ceramic: Characterization and biocompatibility
Wollastonite glass doped with or without 0.5 and 1.0% Fe2O3 was synthesized using a melt-quenching procedure in order to produce new bioactive implants with appropriate magnetic properties. When glasses were sintered at either 1,100 or 1,200°C, combeite (Ca1.543Na2.914Si3O9), pseudowollastonite (Ca3...

| description | Wollastonite glass doped with or without 0.5 and 1.0% Fe2O3 was synthesized using a melt-quenching procedure in order to produce new bioactive implants with appropriate magnetic properties. When glasses were sintered at either 1,100 or 1,200°C, combeite (Ca1.543Na2.914Si3O9), pseudowollastonite (Ca3Si3O9), and wollastonite (CaSiO3) with traces of hematite (Fe2O3) in highest Fe-containing sample were obtained. Upon examining the sintered samples at 1,200°C using a field emission scanning electron microscope (FE-SEM), a variety of irregular grains composed of submicron-sized particles were found. Using dynamic light scattering (DLS), the colloidal stability of wollastonite and its composites with Fe2O3 was investigated. The distribution of particle sizes was between approximately 1 μm and 190 nm, and the zeta potential was negative. The Fe2O3 composition of the sintered samples exhibited a variety of magnetic behaviors. FT-IR reflection was used to assess the produced materials’ biocompatibility after a month of immersion in SBF. The soaked samples confirmed that PO43−{\text{PO}}_{4}^{3-} and Fe(OH)3 were mineralized. Following incubation in SBF, clusters of nanosize calcium phosphate particles were also visible that were spread on the surfaces, as revealed by FE-SEM micrographs and energy dispersive X-ray (EDX) analysis. As the iron content increases, the magnetic characteristics may also be enhanced by the addition of iron. The EDX and FT-IR reflections of the wet sintered samples revealed the mineralization of hydroxyapatite on the surface. Novel magnetic Fe2O3–wollastonite could be very significant since it could open the door to applications as a bone filler and a remedy for hyperthermia. |
