Abstract
In this article, the foamed body of glass was manufactured from the waste borosilicate glass produced by wet pulverization process without additional pretreatment which can be used as a recycling method for waste LCD panel glass. Each 100 g of pulverized waste borosilicate glass with the size of less than 270 mesh were mixed with 0.3 weight fraction of carbon and 1.5 weight fraction of $Na_2CO_3$, $Na_2SO_4$ and $CaCO_3$ and let them foamed for 20 minutes at $950^{\circ}C$ to manufacture the foamed body having the density of less than $0.3g/cm^3$. Additionally, adding $SiO_2$ or $H_3BO_3$ to the mixture enabled the foamed body to have efficient formation of open pores which showed the possibility for producing the foamed body with new functionalities such as sound absorption.
