| 摘 要： | 本研究以铝型材厂煅烧污泥为主原料,研制刚玉/莫来石/钛酸铝复相材料。本实验主要探讨不同配方对复相材料结构与性能的影响,从而确定较佳的配方。用XRD和SEM分析确定各试样的晶相和结构,应用Rietveld quantification软件计算试样中各晶相的含量,测试各试样性能。实验结果,各试样形成3种晶相:α-Al2O3、Al4.59Si1.41O9.7和Al2TiO5,其中Al4.59Si1.41O9.7是主晶相。分析结果,确定NO.4为最佳的配方,其对应晶相含量:α-Al2O3为15.2%、Al4.59Si1.41O9.7为57.6%、Al2TiO5为27.2%;其对应的抗折强度107.63Mpa,一次热震强度抗折强度保持率为41.51%。 |
