Abstract
One of the most significant successes in glass manufacturing is the development of bioactive glass materials, which are closely tied to glass technology. The production of glass and glass-ceramics materials for use in dentistry has received greater attention. Other researchers have explored the CaO-SiO2-CaF2-P2O5-Al2O3 glass system, and the material created has a high mechanical strength when compared to other bioactive glass and glass-ceramics. Although this glass and glass-ceramics are well acknowledged for dental applications, the effect on employing waste materials such as clam shell (CS) and soda lime silica (SLS) glass for dental applications has not been thoroughly researched. Thus, Alumino-Silicate-Fluoride (ASF) glass and glass-ceramics were built and synthesised in this work employing CS and SLS glass as CaO and SiO2 sources, respectively. The traditional melt-quench procedure was used to prepare ASF glass samples. By heating the powder or pallet to a temperature below the melting point to improve its strength by bonding the particles together (Jusoh et al., 2019).The main purpose of this thesis is to study the effect of heat treatment on ASF glass ceramic. There are several temperature differences that will be applied to ASF glass ceramic to be studied in terms of physical and structural properties which is 30 oC, 600 oC, 700 oC, 800 oC and 900 oC. Based on the study that has been done on the ASF sample the range of density is in between 2.226-2.767 g/cm3. While the values of molar volume are in the range of 37.749 to 30.368 cm3/mol. After the samples have been sintered there were samples shrinkage that have been calculated as linear shrinkage. The values of percentage shrinkage are in the range of -0.154 -11.769 %. The results of XRD shown that there was existence of fluorapatite phase in all samples. Meanwhile, FTIR spectra had proven the presence of various bonds, stretching and bending vibrations within the samples before and after sintering.
