This study was conducted to fabricate and characterize of glass–ceramic foam derived from soda-lime silica (SLS) glass waste and eggshell (ES) waste as a foaming agent by using empirical formula [ES] × [SLS]_100−x where x = 1 wt%, 3 wt%, 6 wt%, 9 wt%. The samples undergo a heat-treatment process at temperature 800 °C with a heating rate of 10 °C/min. The properties of the samples were measured by average density measurement and linear expansion. The structural properties were studied by XRD, FESEM and FTIR concerning the different composition of the foaming agent while the mechanical properties were determined by compressive strength using UTM. The lowest density and compressive strength were achieved by 0.326 g/cm³ and 0.04 MPa, respectively with the highest linear expansion at 77.33% by the addition of 3 wt% of ES. Moreover, the cristobalite phase (SiO₂) were identified after the heat treatment process. The production of foam glass–ceramics using SLS glass and ES can be applied to prepare different type of porosity that gives benefit to the environment and energy usage.

多孔玻璃陶瓷中蛋壳废料和回收玻璃的再利用

该研究是通过使用经验公式[ES]×[SLS]进行制造和从碱石灰二氧化硅（SLS）玻璃板废物和蛋壳（ES）废物作为发泡剂衍生玻璃-陶瓷泡沫的特征分析_100-X ，其中x ＝ 1重量％，3重量％，6重量％，9重量％。样品在800°C的温度下以10°C / min的加热速率进行热处理。通过平均密度测量和线性膨胀来测量样品的性质。通过XRD，FESEM和FTIR研究了有关发泡剂组成的结构性能，而机械性能则通过使用UTM的抗压强度来确定。最低密度和抗压强度达到0.326 g / cm ³通过添加3 wt％的ES，其最大的线性膨胀分别为77.33％和0.04 MPa。此外，在热处理过程之后鉴定出方石英相（SiO ₂）。使用SLS玻璃和ES生产泡沫玻璃陶瓷可用于制备不同类型的孔隙度，从而有利于环境和能源使用。
