Fabrication of porous bioactive glass-ceramics via decomposition of natural fibres
AbstractPorous bio glass-ceramics were prepared via natural fibres burning-out process. Glass-ceramics were fabricated by controlled crystallization of suitable glass compositions to give required crystalline phase/s. Porous structure was formed alongside during burning-out of natural fibres. Three glass batches were prepared in the SiO2-CaO-P2O5-K2O-Na2O-CaF2 glass system, then melted, quenched and milled to give fine glass powders. DTA thermograms for the three glass compositions showed crystallization temperatures between 720 and 760Â°C and Tg ranging between 508 and 645Â°C. Porous glass-ceramics were characterized for bulk density, phase evolution and microstructures. Different compositions resulted in different bulk densities and phases that crystallized out. Fluorapatite was found in all glass-ceramic samples, which indicated the biocompatibility and bioactivity and the potential future applications. Microstructures were also different from different heat-treated glass compositions, with more uniform pore size and shape in heat-treated samples containing a higher amount of Na2O and K2O.
