| Abstract | Alumina microspheres have been prepared by spray pyrolysis of Al(NO3)3 aqueous solutions by adjusting the flow rate of air as a carrier gas and the concentration of Al(NO3)3. A mixture of hollow α-Al2O3 microspheres in the range of 200-700 nm in diameter and solid microparticles of smaller size were prepared by pyrolysis of 0.5mol·dm-3 Al(NO3)3 at 1300°C and subsequent calcination at 1300°C for 1h in air. The use of Al(NO3)3 aqueous solutions at concentrations higher than 0.5 mol·dm-3 resulted in the formation of sponge-like α-Al2O3 microspheres containing many closed pores. |
