Kinetic and Thermodynamic Aspects of the Degradation of Ferritic Steels Immersed in Solar Salt.

The study and improvement of the corrosion resistance of materials used in concentrated solar power plants is a permanent field of research. This involves determining their chemical stability when in contact with heat transfer fluids, such as molten nitrate salts. Various studies indicate an improvement in the corrosion resistance of iron-based alloys with the incorporation of elements that show high reactivity and solubility in molten nitrate salts, such as Cr and Mo.

Formation of Olive-like TiO Nanospheres in a Polymeric Mesh by Sol-Gel Method.

Olive-like TiO (titanium dioxide), nanospheres compounds were synthesized. Polysaccharide (1-3 linked β-D galactapyranose and 1.4-linked 3.

Aligned TiO Scaffolds in the Presence of a Galactopyranose Matrix by Sol-Gel Process.

In this work, titanium dioxide scaffolds were synthesized. Titanium isopropoxide (IV) was used as a precursor in its formation, using a polymeric network of galactopyranose as a template. The powder sample obtained was evaluated by scanning tunneling microscopy (STM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) analysis, and thermal gravimetric analysis (TGA-DTA).

Behavior of Ni20Cr Alloy in Molten Nitrate Salts.

This study reports the behavior of the Ni20Cr alloy in molten nitrate salts. Its behavior was evaluated in the eutectic mixture called Solar Salt (binary salt) and in a ternary mixture (90% Solar Salt and 10% lanthanum nitrate). The addition of lanthanum nitrate was performed to determine if the presence of the La cation could act as a corrosion inhibitor.
