In order to study the effect of alloying elements, such as manganese, on the properties of the rust on weathering steels, a series of Mn-goethite samples containing different amounts of Mn were synthesized from ferrihydrite in alkaline media. The sam

Well-crystallized hematite was suspended in water and treated at room-temperature (RT) with sodium borohydride. The product of the reaction is a highly magnetic black powder, which is stable at RT. The NaBH4 treatment converts about half of the hemat
