Toward Decarbonization of the Titanium Industry via Hydrogen Plasma Smelting Reduction
Advanced Science, Volume 13, Issue 1, 5 January 2026.Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Dimensional stability of electric arc furnace slag in civil engineering applications
Journal of Cleaner Production, 2018 Dimensional stability of manufactured aggregates represents a matter of interest for many applications in civil engineering. Past results evidenced how steel slag might be affected by potential swelling, due to several concurring causes linked to the presence of free lime and periclase in their chemical composition.
