Effect of Processing Parameters on the Physical, Thermal, and Combustion Properties of Plasma-Synthesized Aluminum Nanopowders

Abstract

A design of experiments (DOE) was conducted to determine the effects of processing parameters on the physical, thermal, and combustion properties of nanometer scale aluminum powders prepared via an inductively-coupled plasma (ICP) inert gas condensation method. A four-factor, two-level half-fractional factorial array was developed to minimize the number of experiments. Factors chosen for the DOE were plasma power, system pressure, feed rate, and quench rate. Particle size was chosen as the measured response due to its predominant effect on material properties. The results of the DOE showed that feed rate and quench rate have the largest effect on particle size. All synthesized powders were characterized by thermogravimetric analysis/differential scanning calorimetry; field emission scanning electron microscope, Brunauer, Emmet, and Teller; and bomb calorimetry.
