以砂页岩和钢渣为主要原料，SiC为发泡剂，成功地制备了高强度泡沫陶瓷。采用XRF、XRD、SEM、DTA-TG、Micro-CT等分析手段研究了原料配比和热处理温度对复合材料的晶相、孔隙率、力学性能和孔结构的影响。结果表明：当原料中砂页岩的质量分数为94%、钢渣的质量分数为6%时，制备的泡沫陶瓷强度为29.98MPa，体积密度为0.821g/cm 3，总气孔率为67.22%，闭孔率为55.27%，导热系数为0.08W/（m·K）。Micro-CT结果显示，孔隙平均尺寸为267.05μm。孔隙壁厚为18 ~ 42μm，符合正态分布。这种上级性能使其在保温隔热材料、轻质建筑材料等应用领域具有广阔的应用前景。
Foam ceramics with high strength were successfully fabricated by using sand shale and steel slag as the major materials and SiC as foam agent. The influence of raw materials ratio and heat treatment temperatures on crystalline phases, porosity, mechanical properties and pore structures was investigated via XRF, XRD, SEM, DTA-TG, Micro-CT. The results indicate that the raw materials composed of 94 wt% sand shale and 6 wt% steel slag enable the fabrication of foam ceramics possessing strength of 29.98 MPa, bulk density of 0.821 g/cm3, total porosity of 67.22%, closed porosity of 55.27% and thermal conductivity of 0.08 W/(m·K). Micro-CT result shows that the pores with an average size of 267.05μm are isolated. Pore wall thickness conforms to normal distribution, and it ranges from 18 to 42μm. The superior property makes it promising high-strength and lightweight material in application fields, including thermal insulation materials and lightweight building materials.
