Pure titanium nanoparticles were synthesized by utilizing an Electromagnetic Levitation Melting Gas Condensation (ELM-GC) method. Pure bulk titanium samples were melted and evaporated by electromagnetic levitation technique in an inert gas atmosphere in a silica tube. Titanium nanoparticles were formed from ascending vapor by employing high purity argon and helium as carrier gases and cooling agents. Particle size and morphology of the produced nanoparticles were studied by Field-Emission Scanning Electron Microscopy (FE-SEM) and Dynamic Light Scattering (DLS) analysis. Resultsshowed almost spherical nanoparticles with a narrow size distribution under both cooling atmospheres.The purity of the produced titanium nanoparticles was confirmed through powder X-ray diffraction (XRD) as well as X-ray fluorescence (XRF), and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) analysis. As to the impact of carrier gas, titanium nanoparticles synthesized under helium atmosphere had smaller particle size with narrower particle size distribution compared to those produced in argon. Average particle size of synthesized titanium nanoparticles under Ar and He atmospheres were about 42 and 31 nm, respectively.

“…To overcome these limitations and enable nanoscale Ti production, various techniques have been developed. Maeng et al [15] employed a gas-phase co-flow flame method to produce Ti particles of 20-100 nm diameter. A thin layer of NaCl was coated onto the surface via combustion of a TiCl 4 -Na mixture, and then removed in vacuum by a post heat treatment at 800 °C.…”

Nanoscale metallic titanium (Ti) offers unique energetic and biocompatible characteristics for the aerospace and biomedical industries. A rapid and sustainable method to form purified Ti nanocrystals is still in demand due to their high oxygen affinity. Herein, we report the production of highly purified Ti nanoparticles with a nonequilibrium face center cubic (FCC) structure from titanium tetrachloride (TiCl4) via a capacitively coupled plasma (CCP) route. Furthermore, we demonstrate a secondary H2 treatment plasma as an effective strategy to improve the air stability of a thin layer of nanoparticles by further removal of chlorine from the particle surface. Hexagonal and cubic-shaped Ti nanocrystals of high purity were maintained in the air after the secondary H2 plasma treatment. The FCC phase potentially originates from small-sized grains in the initial stage of nucleation inside the plasma environment, which is revealed by a size evolution study with variations of plasma power input.
