Characterization Study on Alumina Nanoparticles Synthesised by Solution Combustion Method

In recent years, nanostructured metal oxide materials have great interest due to their physical, chemical, mechanical and electrical properties [1,2]. Nano alumina (Al2O3) as a type of metal oxide is frequently used in several applications such as a catalyst [3], sensors [4], abrasive materials and etc., [5] due to its high surface area and porosity [3]. Several methods such as chemical precipitation, sol-gel, milling, spray drying, solution combustion etc. can be used for obtaining alumina nanoparticles [1]. Solution combustion synthesis of metal oxide materials is a novel and useful method [4]. This technique gives a chance for simple, inexpensive and time-saving production process than the other synthesis options [5]. Moreover, nanoparticles produced by this method have higher purity, better chemical homogeneity and smaller size [1]. In the present study, alumina nanoparticles were synthesized via solution combustion method using aluminum nitrate (Al(NO3)3) as an oxidizer and utilizing urea and glycine as a fuel. The effects of the fuel type and initial fuel amount on chemistry and physiology on particles were investigated during the characterization studies. In characterization step, X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric/differential thermal analysis (TG/DTA) were used to evaluate relevant conditions.
