Abstract

Silica-based glass-ceramics have been fabricated in this work using soda-lime- silica (SLS) glass waste. The quarternary glass-ceramic was fabricated with composition xMgO: (0.5-x)ZnO: (0.2)B2O3: (0.3)SiO2 ; x = 0.01, 0.03 and 0.07 mole using melt quenching technique. The glass samples were sintered at 27°C, 700°C and 800°C. The variation composition of MgO on physical properties which includes density measurement and linear shrinkage measurement had been studied. The density of glass samples that are treated at room temperature and 700°C is almost having the same values which about 1.8g/cm-3 for different percentage of MgO. Then, density for samples that are treated at 800°C had decreased from 1.855g/cm-3 to 1.658g/cm-3 and increased again to 1.815g/cm-3 for different percentage of MgO. Linear shrinkage of glass samples with variation composition of MgO at room temperature is zero because the samples are not heated which have no decreasing in diameter. The samples that had been treated at temperature 700°C and 800°C had increased and decreased in increasing the composition of MgO.
