| 摘 要： | A small amount of mineralizer MgO was added into Al2TiO5 synthesized from the sludge of aluminum factory to form Al（2-x）Mg（x＋y）Ti（1-y）O（5-0.5x-y） solid solution and inhibit the decomposition of Al2TiO5 solid solution. It increased the content of Al2TiO5 solid solution and improved the thermal stability of materials. In this work,XRD and SEM methods were adopted to characterize the crystalline structure and microstructure of each kind of sample. Rietveld Quantification method was used to determine the content of crystalline phases in each sample. Results show as follows： the optimal addition concentration of MgO was 2.0%,and the corresponding content of Al2TiO5 solid solution which displayed irregular bulk shape was 100%; the addition of mineralizer MgO could enhance the flexural strength and thermal stability of Al2TiO5 solid solution materials. The optimal addition concentration of MgO determined by performance analysis was 2.0%,and its corresponding retention rate of thermal-shock flexural strength was 86.4%. Structure analysis and performance analysis resulted in good accordance.

| Abstract: | A small amount of mineralizer MgO was added into Al_2TiO_5 synthesized from the sludge of aluminum factory to form Al_(2-x)Mg_(x+y)Ti_(1-y)O_(5-0.5x-y), solid solution and inhibit the decomposition of Al_2TiO_5 solid solution. It increased the content of Al_2TiO_5 solid solution and improved the thermal stability of materials. In this work, XRD and SEM methods were adopted to characterize the crystalline structure and microstructure of each kind of sample. Rietveld Quantification method was used to determine the content of crystalline phases in each sample. Results show as follows: the optimal addition concentration of MgO was 2.0%, and the corresponding content of Al_2TiO_5 solid solution which displayed irregular bulk shape was 100%; the addition of mineralizer MgO could enhance the flexural strength and thermal stability of Al_2TiO_5 solid solution materials. The optimal addition concentration of MgO determined by performance analysis was 2.0%, and its corresponding retention rate of thermal-shock flexural strength was 86.4%. Structure analysis and performance analysis resulted in good accordance. |
