THE HYDRATION OF THE ALUMINATES OF CALCIUM: III. THE HYDRATION OF THE 5:3, 1:1, AND 3:5 CALCIUM ALUMINATES

, 1943
The hydration of the aluminates of calcium in saturated steam at 150° and 105 °C. was studied. A method was developed for the quantitative estimation of chemically combined and free hydrated alumina in steam treated mixtures.

Corrosion and Passivation: An Intimate Struggle for Durable Non‐Aqueous Multivalent Metal Batteries

National Materials, EarlyView.
In multivalent metal batteries, corrosion and passivation are intrinsically coupled. Anodes and current collectors pose conflicting interfacial demands: ion‐ versus electron‐conductivity. This review deciphers their intricate interplay and discusses current strategies to balance these mechanisms for achieving durable battery performance.

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Can iron-doped calcium aluminates activate ternesite hydration?

The hydration inertness of ternesite (C5S2Š) is the primary barrier to the promotion of Ternesite-Ye'elimite Cement (TYC). This study investigated the potential of iron-doped calcium aluminates to activate the hydration of TYC systems, with particular ...

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

steel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.
