Description: technologyComment of titanium production (GLO): Primary titanium metal is produced mainly by Kroll process. In this batch process, titanium tetrachloride (TiCl4) is reduced with magnesium under inert atmosphere creating a sponge like titanium metal solid which is refined by vaccum arc remelting. The Kroll process is characterized by multiple steps for which many are energy and labor intensive. Main steps include batch reduction, processing, vaccum distillation and remelting. Main batch reduction takes place in a steel reactor filled with argon where the magnesium is melt at temperature between 850°C-950°C. The titanium chloride (TiCl4) is fed, or blown in as vapor, into the reactor. The reduction is a highly exothermic reaction, thus little energy input is required for it to take place. Reaction is as follow: TiCl4(l or g) + 2 Mg(l) = Ti(s) + 2 MgCl2(l). During the processing the reaction by-product, molten magnesium chloride (MgCl2), is remove from the reator periodically during the reaction. The magnesium and clhoride from this by-product are recovered using electrolysis and re-used. Main product from the process is a sponge like titanium (Ti(0)). Vaccum distillation is then use to purified the crude sponge removing residual metal chlorides and magnesium. This process takes place at temperature between 900°C and 1000°C. The residuals are recovered by condensation. The purified titanium sponge is refined using vacuum arc remelting.

Comment: This is a market activity. Each market represents the consumption mix of a product in a given geography, connecting suppliers with consumers of the same product in the same geographical area. Markets group the producers and also the imports of the product (if relevant) within the same geographical area. They also account for transport to the consumer and for the losses during that process, when relevant. This is the market for 'titanium sponge', in the Global geography. This market contains no transport or losses, as they are irrelevant for the delivered product. This market is supplied by the following activities with the given share: titanium production, GLO: 1.0 generalComment of titanium production (GLO): This dataset represents the production of 1 kg of titanium. Primary titanium metal is produced mainly by the Kroll process, which produces purified titanium sponge. The titanium sponge can then be refined using vacuum arc remelting. This dataset models the vacuum arc remelting step. The previous steps are modelled in the titanium tetrachloride production dataset and the titanium sponge production dataset.
