by the precipitation reaction of aluminum sulfate and urea, which was calcined to get ultrafine α-Al2O3. The effects of mole ratio of CO(NH2)2 to Al2(SO4)3, initial concentrations of Al2(SO4)3, reaction temperature.... The results show that spherical ultrafine α-Al2O3 powder with non-aggregation and the average particle size of about 2 μm was produced under the conditions: mole ratio of CO(NH2)2 to Al2(SO4)3 is 10......
