| Abstract: | A new method for preparing Ni coated alumina composite particles named coordination homogeneous precipitation-thermal reduction with carbon was researched,and Ni coated Al_2O_3 core-shell composite particles were prepared. The composite particles were characterized by TEM and XRD. The size of composite particles were uniform with average particle size less than 0.3 μm. This new method had the advantages of convermient operation, high utilization rate of raw materials, and no impurity. |
