A characteristic CaO-Al₂O₃-SiO₂ based foam ceramic was prepared by melt-foaming with solid wastes as main raw materials. The similarity to sandwich hole wall microstructure of this novel thermal insulating material was presented and the relationships between this unique microstructure and porosity, density, thermal conductivity and strength were discussed. Comparing the measured and theoretical values with that of the traditional foam ceramic, it can be found that, for the matching of fine skeleton with hole wall, this original sandwich structure can reduce thermal conductivity and increase flexural strength effectively.

新型废泡沫陶瓷的独特微观结构和隔热性能

以固体废弃物为主要原料，通过熔融发泡制备了具有特征性的CaO-Al ₂ O ₃ -SiO ₂基泡沫陶瓷。提出了这种新型保温材料与夹层孔壁微观结构的相似性，并讨论了这种独特的微观结构与孔隙率，密度，导热率和强度之间的关系。将测量值和理论值与传统泡沫陶瓷的测量值和理论值进行比较，可以发现，为了使细骨架与孔壁匹配，这种原始的夹层结构可以有效降低导热系数并提高抗弯强度。
