Preparation of Hollow Alumina Microspheres by Ultrasonic Spray Pyrolysis.

Journal of the Ceramic Society of Japan, 2002
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°
