| Abstract: | The aluminum chromium slag and wasted MgO-C brick powder are taken as the main starting materials,the magnesium aluminum spine（MgAl2O4） is obtained by solid state reaction.The main crystalline phase and microstructure are examined by X ray diffraction,scanning electron microscopy and X Pert plus software.The result shows that the grain growth of magnesium aluminum spine is complete and clear,the appearance is typical octahedral morphology,the arrangement is dense and the content of MgAl2O4 is 92%when the ratio of wasted MgO-C brick and aluminum chromium slag is 5: 1 and firing temperature is 1 400℃. |
