Abstract
The bioactivity properties of porous cordierite (C), pseudo-wollastonite (PW), and cordierite/pseudo-wollastonite (CPW) biocomposite ceramics were studied. Cordierite was prepared via melting, and pseudo-wollastonite was prepared via the wet milling method. Meanwhile, the cylindrical porous of cordierite (C), pseudo-wollastonite (PW), and cordierite/pseudo-wollastonite (CPW) biocomposite was fabricated using a gel-casting method, then sintering at 1250 °C for two hours. The X-ray analysis and SEM techniques were applied to find the phase and microstructure. The bioactivity properties of porous cordierite (C), pseudo-wollastonite (PW), and cordierite/pseudo-wollastonite (CPW) biocomposite were determined after soaking for seven days in the simulated body fluid (SBF) solution, which appearance layer of hydroxyapatite (HA) that exhibits a biological activity with the present of pseudo-wollastonite as compared with porous cordierite. The XRD patterns showed that the crystallinity of C and PW samples has decreased due to the HA formation after seven days of soaking. SEM tests revealed more HA microstructures in porous pseudo-wollastonite samples than in porous cordierite/pseudo-wollastonite. The effect of cordierite and pseudo-wollastonite in biocomposite ceramics is described in this paper.
