Influence of temperature on the stability of titanium nanocluster in TiCl

\nSouth Africa is one of the largest producers of titanium-bearing minerals in the world, accounting for 18% of rutile production and 12% of ilmenite production. However, the country has yet to establish a noticeable advantage in the production of titanium, even though the mineral is emphasised as crucial for the economy. To date, attempts are being made, both experimentally and theoretically, to enhance the production of titanium. This is guided by the reduction of TiCl4 to form intermediates such as TiCl3 through the Kroll process. In this study, classical molecular dynamic calculations were performed to understand the geometry of the cluster in two TiCl3 polymorphs (α-TiCl3 and β-TiCl3 mediums). It was found that the cluster maintains its pentagonal bipyramid geometry at the temperature range of 50 – 2000 K for both mediums. This indicates that the cluster is stable, and geometry is preserved in the mediums. The results obtained in this study provide more insight into the growth/evolution of titanium in TiCl3 medium for titanium production processes.\n
