Effects of pertinent operating parameters on the size of iron nanoparticles synthesised by chemical vapour condensation method applying experimental design procedure

Nanosized iron powders have been synthesised by the chemical vapour condensation (CVC) method. The effects of various operating parameters, such as decomposition temperature, bubbler temperature, carrier gas flow rate, precursor flow rate and pressure on the particle´s size and properties, were investigated. The phase analysis and morphology of samples were determined by X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. The effects and contributions of the process pertinent parameters on particle size and interactions between the parameters were determined using Taguchi experimental design method. It was observed that the decomposition temperature was the most significant process parameter affecting the particle size.
