Synthesis of titanium-silver bimetallic nanoparticlesby thermal plasma method

In the present paper, the micron-size silver and titanium powder with desired weight ratios is used to producethe silver-titanium nanocomposite using the self-developed thermal plasma equipment. the mixture is fed intothe plasma torch flame by the powder feed system and argon carrier gas. after evaporation, the particles arecooled inside the cooling chamber and collected from the surface of the water-cooled double-walled chamber.the production of titanium-silver bimetallic nanoparticles is achieved in two ways: the cooling chamber isonce filled with argon and once with atmospheric air. the nanoparticles are analyzed using scanning electronmicroscope (sem), energy dispersive x-ray spectroscopy (eds), and x-ray diffraction (xrd) methods toidentify the nanoparticle size distribution, morphology and chemical composition properties. the morphology ofthe produced nanocomposites is spherical and their average size is 30 nm. the results indicate that the averagesize of nanoparticles produced in the presence of air is smaller than those in the presence of argon.
