| dc.description.abstract | Bioactive glass (BG) is one of the biomaterials that are widely used in various biomedical applications such as dental implant, due to its excellent ability to bind with tissue through a bonding formation with apatite layer. However, BG demonstrated low mechanical strength to withstand external force. In this study, bioactive glass-cordierite ceramic (BG-cord) composite was developed to overcome this issue. BG and cordierite were synthesized using glass melting method prior to BG-cord fabrication in pellet shape. In the fabrication process, the milling time of cordierite (0.5 to 5 h), the composition of BG and cordierite, and the sintering temperature of BG-cord (600 – 1000 ºC) were studied. An improvement in the mechanical properties of BG was observed with the addition of cordierite, proven by the superior diametral tensile strength (DTS) of BG-cord to BG. The DTS of BG increased from 6.29 MPa to 14.01 MPa upon milling with 30% cordierite for 3 hours. A further increase in DTS value from 14.01 MPa to 30.54 MPa was recorded when the BG-cord was sintered from 600 °C to 925 °C. The optimum BG-cord exhibited physical characteristics of 2.33 g/cm3 bulk density, 8.92% porosity, 30.54 MPa DTS, 93.75 MPa compressive strength, and 153.93 Hv hardness. A positive response of bioactivity performance was observed in the BG-cord with apatite formation as detailed in the in-vitro analysis using scanning electron microscope (SEM). X-ray diffraction (XRD) analysis revealed apatite peaks proved the formation of apatite. The increase of intensity of P-O and C-O spectra from Fourier transform infrared (FTIR) analysis after bioactivity test also proved the apatite formation. As a conclusion, the BG-cord produced from the current study has potential application as a dental implant material. | |
