Description
This dataset represents a product that is titanium sponge, a porous metallic titanium element prepared from refined titanium tetrachloride via a combined magnesium-reduction–vacuum-distillation method. Its appearance is usually light-grey granular, with a clean surface and no visible inclusions, and it has the physical characteristics of being porous and loose in structure. Titanium sponge is an unformed primary titanium metal raw material that must undergo melting and densification treatment before it can be subjected to industrial deep processing; it is the core basic raw material for preparing titanium and titanium-alloy ingots, titanium powder and various titanium products, and is also an important base material for industrial titanium-alloy production and processing. The upstream raw material of this product is refined titanium tetrachloride, and the downstream, through the melting process, can be processed into products such as titanium ingots and titanium-alloy billets, being widely applied in aerospace, high-end equipment manufacturing, chemical corrosion protection, medical devices and other fields; it is a key core intermediate product in the deep-processing stage of the titanium industry. The dataset includes the main raw and auxiliary materials, energy and wastes in the production process; infrastructure such as the manufacture of production equipment and plant construction is not included within the boundary of the dataset; the data inventory is formed by merging data from multiple sources.
Activity Description
The entire production process includes a combined magnesium reduction-vacuum distillation method. Molten metal magnesium is added to the reactor, refined titanium tetrachloride is continuously added, and the temperature of the reduction reaction is controlled between 800 and 1000°C. Magnesium chloride is discharged regularly according to the feeding rate and the pressure change in the reactor. After the reduction reaction is completed, it is transferred to the distillation operation, and the excess metal magnesium and residual MgCl2 are condensed in the reactor to obtain pure titanium sponge.
Process Description
Titanium sponge is a kind of porous titanium metal produced by metal thermal reduction method. It is usually light gray granular in shape, with a clean surface and no visible inclusions. Titanium sponge is porous and has a loose structure. It is the basic raw material for titanium and titanium alloy ingots, titanium powder and other titanium products. It needs to be smelted before it can be used for industrial processing. It is an important basic material for the preparation of industrial titanium alloys.

Add molten metal magnesium into the reactor, continuously add refined titanium tetrachloride, and control the temperature of the reduction reaction at 800 to 1000°C. Magnesium chloride is discharged regularly according to the feeding rate and the pressure change in the reactor. After the reduction reaction is completed, it is transferred to the distillation operation, and the excess metal magnesium and residual MgCl2 are condensed in the reactor to obtain pure titanium sponge.
