Specific Surface Area Increment of Alumina Nanoparticles Using Mineral Fuels in Combustion Synthesis

Abstract

Ammonium carbonate and ammonium sulfate have been proposed and used as two new fuels for synthesizing gamma alumina nanoparticles. The prepared samples have been characterized by X-ray diffraction (XRD), 2 N adsorption (BET) and Transmission electron microscopy (TEM). A comparison has been made between the properties of the nanoparticles synthesized by these two fuels and other conventional fuels. These two mineral fuels showed to be suitable for replacing organic fuels in combustion synthesis because they reduce the size and increase specific surface area of alumina nanoparticles effectively.
