Calcium phosphate glasses have a potential use as bone substituting applications,
because of their chemical composition is closely similar to that of natural bone. The implant
glass can be slowly replaced by regenerating tissue and has good biocompatibility and
non-toxicity. In this experimental study, porous bioglass-ceramics were prepared via
natural fibers (wood dust) burning-out process. Three glass batches were prepared in the
ZrO2/Al2O3-CaO-P2O5 glass system, then melted, quenched and milled to give fine glass
powders. Bioglass composites were sintered in a furnace at different sintering temperatures
(750C, 850C and 950C) for 3 hours. The sintered bioglass samples were analyzed by
field emission scanning electron microscopy (FE-SEM), energy-dispersive spectroscopy
(EDS) and X-ray diffraction (XRD) for further investigation of grain morphology, shape,
size and phase formation. The bulk density, the apparent porosity and water absorption
of the sintered samples were measured using the Archimedes’ principle. The mechanical
properties (micro-hardness in this case) and in-vitro dissolution behavior of those bioglasses
were investigated and discussed.
