摘要

以硅锰渣 (SM) 和氟石膏 (FG) 为原料,以 SiC 为发泡剂,合成了高强度泡沫陶瓷。研究了焙烧温度和 FG 含量对泡沫陶瓷的相结构、微观结构和物理性能的影响。通过 X 射线衍射和扫描电子显微镜对样品进行了表征。结果表明,增加 FG 含量可降低基体熔点,促进晶体生长,提高抗压强度,并形成均匀的孔隙结构。当 FG 含量为 11% 时,在 1130°C 烧制温度下制备的陶瓷密度为 0.56 g/cm3,孔隙率为 78.45%,抗压强度为 3.05 MPa。这项研究探讨了如何使用 FG 作为具有成本效益的硼砂替代品,展示了一种利用硅锰渣和 FG 协同作用制备泡沫陶瓷的可持续方法。

Preparation and characterization of foamed ceramics from silicomanganese and fluorgypsum waste
High‐strength foamed ceramics were synthesized employing silicon‐manganese slag (SM) and fluorgypsum (FG) as raw materials, with SiC serving as the foaming agent. Investigations into the influence of firing temperature and FG content on the phase structure, microstructure, and physical properties of foam ceramics were conducted. Characterization of the samples was performed through X‐ray diffraction and scanning electron microscopy. Results indicate that an increase in FG content lowers the matrix melting point, promotes crystal growth, enhances compressive strength, and forms a uniform pore structure. At an FG content of 11%, ceramics prepared at a firing temperature of 1130°C exhibit a density of 0.56 g/cm3, porosity of 78.45%, and compressive strength of 3.05 MPa. This study explores the use of FG as a cost‐effective alternative to borax, demonstrating a sustainable approach for foam ceramics preparation using silicomanganese slag and FG synergy.
