尽管有大量研究使用固体废物成功制备出了发泡陶瓷，但材料的结构、性能与其原料成分息息相关。在不同的助熔剂(Na2CO3、K2CO3和B2O3)和Al2O3/SiO2下，系统考察了锂瓷土矿选矿尾矿-高硼硅废玻璃基发泡陶瓷的结构、晶相及其性能。结果表明，在原料配比为70%锂瓷土选矿尾矿+30%高硼硅废玻璃，烧结温度为1 150℃，保温时间为60 min条件所制成样品的平均孔径为0.77 mm、吸水率为4.9%、表观孔隙率为5.1%、体积密度为0.99 g/cm3、抗压强度为7.2 MPa)，额外添加助熔剂的种类和含量均会显著影响液相生成及孔隙结构：Na2CO3的加入(0%～7%)可促进液相形成，增大孔径并降低体积密度和抗压强度，但过量(>5%)会导致塌孔，反使体积密度和抗压强度增大；K2CO3(0%～4%)通过降低熔体黏度，显著提升表观孔隙率和吸水率，但过量液相会填充孔隙，导致二者下降；B2O3(0%～7%)通过弱化熔体网络结构，降低膨胀阻力，使体积密度和抗压强度持续降低，吸水率则呈先降后升趋势。不同Al2O3/SiO2比例对性能影响表现为：Al2O3的引入可增强骨架强度，从而使抗压强度显著提升，而SiO2的引入则可通过促进液相生成从而降低体积密度，并提升吸水率与表观孔隙率。此外，XRD分析表明，助熔剂可抑制石英晶相形成，促进无定形玻璃相生成，而Al2O3/SiO2比例对晶相无明显影响。研究结果为锂瓷土尾矿的高效资源化提供了理论支撑，同时为低成本、高性能发泡陶瓷的工业化生产奠定了技术基础，具有显著的环保与经济价值。
