Overview

This research addresses the significant challenges of waste disposal and the need for sustainable production in the ceramics industry by introducing an approach to fabricating calcium-alumino-silicate-fluoride (CASF) based glass ceramics. Using recyclable materials such as waste soda-lime-silicate (SLS) glass and clam shells (CS) as primary precursors, a controlled melt-quenching process was employed to investigate how varying the CaO/CaF 2 ratios influences the physical and structural properties of CASF glass ceramics. The waste materials and CASF glass ceramics were analyzed using X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transforms infrared (FTIR), Scanning electron microscopy (SEM), and Energy dispersive X-ray (EDX) spectroscopy. XRD indicated the crystalline structure in all CASF glass ceramics samples while FTIR spectroscopy detected several linkages, including PO 4 3− , Si-OH, Si-O-Si, CO 2 , and O-H indicating the development of CASF glass ceramics. SEM analysis showed a non-uniform distribution of particles and EDX analysis, shows the calcium-to-phosphate molar ratio (Ca/P) of CASF glass ceramics. The glass ceramics labeled as G6 possessed better properties, with a minor crystalline phase identified as fluorapatite (Ca 5 (PO 4 ) 3 F), which is compatible with the commercial bioglass. These results demonstrate a cost-effective waste-derived bioglass system used in biomedical fields.
