nano-alumina; homogeneous precipitation method; TiO2/BaO-doping; specific surface area
【摘要】
A nano-alumina with high specific area was prepared using a homogeneous precipitation method with titanium dioxide and barium oxide as modifying additives. Results showed that 5 wt% TiO2 or BaO added in the alumina gels can decrease the particle size and increase the specific area, but excessive TiO2 or BaO could deteriorate the properties of α-Al2O3.
