Soda lime silica (SLS) waste as the source of silica (SiO) and ark clamshell (ACS) as the foaming agent has been utilized to fabricate the low-cost and lightweight foam glass-ceramics. A series of 1 and 6 wt% foam glass-ceramics were successfully prepared by the conventional solid-state sintering method at various sintering temperatures for 60 min. The bulk density of the samples has achieved minimum density (1.014 g/cm) with maximum expansion (62.31%) at 6 wt% of the ACS content sintered at 800 °C for 60 min. The bulk density increases while the linear shrinkage and total porosity decrease with the progression of ACS contents and sintering temperature, where the results correspond with the FESEM micrograph. The result of XRD and FTIR transmittance spectra have shown that the formation of wollastonite crystal has occurred starting at 6 wt% of the ACS content sintered at 800 °C for 30 min. The highest mechanical performance (3.90 MPa) with an average total porosity (8.04%) is observed for the sample containing 1 wt% of ACS. It can be concluded that the composition of foam glass-ceramics (1 and 6 wt%) and sintering temperatures give significant results to the structural, physical, and mechanical properties of the fabricated foam glass-ceramics.
以钠钙硅石（SLS）废料作为二氧化硅（SiO）来源，以方舟蛤壳（ACS）作为发泡剂，用于制备低成本、轻质的泡沫微晶玻璃。通过传统的固态烧结法，在不同烧结温度下保温60分钟，成功制备了一系列1wt%和6wt%的泡沫微晶玻璃。在800℃下烧结60分钟、ACS含量为6wt%时，样品的堆积密度达到最小密度（1.014g/cm），最大膨胀率为62.31%。随着ACS含量和烧结温度的升高，堆积密度增加，线性收缩率和总孔隙率降低，这一结果与场发射扫描电子显微镜（FESEM）显微照片相符。X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）透射光谱结果表明，在800℃下烧结30分钟、ACS含量为6wt%时开始形成硅灰石晶体。对于含有1wt%ACS的样品，观察到最高的力学性能（3.90MPa），平均总孔隙率为8.04%。可以得出结论，泡沫微晶玻璃的组成（1wt%和6wt%）和烧结温度对所制备的泡沫微晶玻璃的结构、物理和力学性能有显著影响。
