Synthesis of titanium-silver bimetallic nanoparticles by thermal plasma method
In the present paper, the micron-size silver and titanium powder with desired weight ratios is used to produce
the silver-titanium nanocomposite using the self-developed thermal plasma equipment. The mixture is fed into
the plasma torch flame by the powder feed system and argon carrier gas. After evaporation, the particles are
cooled 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 is
once filled with argon and once with atmospheric air. The nanoparticles are analyzed using scanning electron
microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and X-ray Diffraction (XRD) methods to
identify the nanoparticle size distribution, morphology and chemical composition properties. The morphology of
the produced nanocomposites is spherical and their average size is 30 nm. The results indicate that the average
size of nanoparticles produced in the presence of air is smaller than those in the presence of argon.
