Pure epsilon-phase iron oxide was unexpectedly discovered in the glaze of silvery Jian bowls made 1,000 years ago, a group of researchers announced this week.

Ancient Chinese tea bowls might hold the recipe for a rare form of iron oxide that scientists have had a hard time making in the lab. Pure epsilon-phase iron oxide was unexpectedly discovered in ...

Last year UO chemist Paul Kempler and his team reported a way to create iron with electrochemistry, using a series of chemical reactions that turn saltwater and iron oxide into pure iron metal.

A new low-temperature electrochemical process that produces metallic iron from iron oxide and saltwater could help clean up steelmaking’s act (Joule 2024, DOI: 10.1016/j.joule.2024.01.001).

Electrolysis produces iron a different way. The iron ore is dissolved in a solvent of silicon dioxide and calcium oxide at 1600°C and an electric current passed through it.

Instead of burning coal, the researchers use electricity to transform iron oxide into pure iron using a saltwater-based system. This eliminates the need for carbon-heavy fuels.

It was found then that treatment of specimens of enamelling iron (C = 0·01, Ni = 0·1, Cr = 0·1, Si = 0·005, Mn = 0·14, trace Cu, Sn, As, Al and Ca) in hot dilute hydrochloric acid gave fairly ...

This converted the material's inherent iron oxide into 98 percent pure iron, using polymer resins present within the powder as a source of carbon.
