| 摘 要： | 以TiO2和BaO为改性剂,采用均相沉淀法制备出了高比表面积的纳米氧化铝.研究结果表明:添加质量比为5%的TiO2或BaO可以减小颗粒尺寸,增大比表面积.但过量的TiO2或BaO会恶化α-Al2O3的性能.

| Abstract: | The nano-alumina with high specific area was prepared by using homogeneous phase precipitation method with Titanium dioxide and barium oxide as modifying additives.The results showed that 5% TiO_2 or BaO added in the alumina gels can reduce the particle size and increase the specific area,but excessive TiO_2 or BaO deteriorate properties of a-Al_2O_3. |

| Keywords: | nano-alumina homogeneous precipitation method doping specific surface area |
