In this research, an alumino-borosilicate foamed glass with sound absorption property was prepared using the waste borosilicate glass obtained from the recycling process of waste liquid crystal display (LCD) panel. A 100 g of pulverized waste borosilicate glass with the particle size of under 325 mesh, was mixed with 0.3 g (wt/wt) of graphite, each 1.5 g (wt/wt) of Na2CO3, Na2SO4 and CaCO3 as a foaming agent, and 6.0 g (wt/wt) of H3BO3 and 3.0 g (wt/wt) of Al2O3 as a pore control agent. Following mixture was under the foaming process for 20 minutes at a foaming temperature of 950 °C. The result yielded the foaming agent with 45% of the opened porosity and 0.5-0.7 of the sound absorbing coefficient. This alumino-borosilicate foamed glass with the sound absorption property showed excellent physical and mechanical properties such as density of 0.21 g/cm3, bending strength of 55 N/cm2 and compression strength of 298 N/cm2 which can be ideally used as sound absorption materials with heat-resisting and chemical-resisting property.
