12 December 2007 Chemists in Japan and France have produced a new iron oxide with a sheet-like structure that could be used in fuel cells and sensors. The team produced the compound by gentle reduction in a way that may also yield other unusual and potentially useful crystalline structures. Hiroshi Kageyama from the University of Kyoto and colleagues started with a conventional…

Uranium can take many chemical forms. In nature, uranium is generally found as an oxide, such as in the olive-green-colored mineral pitchblende. Uranium oxide is also the chemical form most often used for nuclear fuel. Uranium-fluorine compounds are also common in uranium processing, with uranium hexafluoride (UF6) and uranium tetrafluoride (UF4) being the two most common…

Iron combusts in oxygen to form various iron oxides, mainly iron() oxide: 4 Fe (s) + 3 O2 (g) == 2 Fe2O3 (s) Iron in its usual bulk solid form will only burn when in pure oxygen with when a great deal of heat is supplied. This is what a cutting torch does. As we can see in this demo, however, when iron is subdivided finely it burns readily enough in air. We also see that when…

Iron oxide materials yield pigments that are nontoxic, nonbleeding, weather resistant, and lightfast. Natural iron oxides include a combination of one or more ferrous or ferric oxides, and impurities, such as manganese, clay, or organics. Synthetic iron oxides can be produced in various ways, including thermal decomposition of iron salts, such as ferrous sulfate, to produce…

Synthetic red Iron Oxide Pigments were first made in a Laboratory setting by the 18th century. This pigments were given the name Mars Red. These pigments contained all the properties of their counterparts, i.e. Natural Iron Oxide Pigments. These properties included durability, permanence etc. Form 19th century, the manufacturing of these synthetic iron oxide pigments started…
