“…Previously, several researchers had studied the feasibility of producing titanium powders from TiCl 4 using plasma. Miller et al [3] proposed equilibrium calculations of Ar-Ti-Cl-H by solving equilibrium constant equations of 101.325 kPa total pressure. It seems that no polyatomic species existed above 4,000 K and the experimental results show that TiCl 4 was reduced to TiCl 3 by H 2 using RF plasma.…”

In this study, the production of titanium powder via hydrogen reduction of titanium tetrachloride by inductively coupled radio frequency plasma was investigated. While titanium tetrachloride is hard to be reduced by hydrogen thermodynamically, dissociated hydrogen radical which formed from hydrogen gas passing through the plasma can react with titanium tetrachloride to form hydrochloric acid and subsequently produce titanium. The frequency of generator used in this experiment was 13.56 MHz and input power was varied. The characteristics of the powder such as powder size, size distribution, and phases were analyzed with x-ray diffractometer, field emission scanning electron microscope, energy dispersive x-ray spectrometer and transmission electron microscope. The deposited height of titanium powders, after 4 minutes reaction, were 4.004 μm and loosely attached that could be easily collected. The morphology of powders was found to be more spherical with the increase in applied input power. Most of the powders were composed of titanium and oxygen. The average diameter of powders was approximately 200 nm.

The feasibility of producing titanium metal from titanium tetrachloride in a thermal plasma under equilibrium and adiabatic expansion conditions has been theoretically investigated. Free energy minimization and adiabatic expansion calculations to simulate a nozzle expansion were used to stud), the practicality of production. The crucial requirements for tbe production of titanium powder from TiCI4 and 1"12 appear to be rapid quenching of the plasma gas at high temperature (e.g., 3700 K) and appropriate reactant concentrations. Quenching of the plasma gas and production of titanium powder can be achieved by adiabatic expansion througb a nozzle. Preliminary experimental data indicate that titanium powder of approximately 5 nm in size can be produced in an argon plasma using a nozzle expansion approach.
