英文摘要 | In this paper, weakly agglomerated and well dispersed alpha-Al2O3 powders were synthesized by a novel spray precipitation method. It was demonstrated that the as-prepared powders exhibited better dispersity than powders from conventional precipitation due to the increased phase contact and reaction area during the precipitation process. The effects of different titration ways, calcination temperature and holding time on the morphology, phase composition and sintering behaviour of Al2O3 powders were systematically investigated. Weakly agglomerated and well crystallized alpha-Al2O3 powders were obtained when the as-prepared precursors were calcined at 1150 degrees C for 2h in air. The average particle size of alpha-Al2O3 powders with higher sintering activity was approximately 68.6 nm, and the specific surface area was above 22.4 m(2) g(-1). |
