They are black magnetic solids that are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite. Iron oxide is an inorganic compound with the chemical formula Fe2O3. It is one of the 3 major oxides of iron, the others being iron (II) oxide and iron (III) oxide. It is also known as rust, ferric oxide, or hematite 氧化铁是由铁和氧组成的化合物。它们是黑色的磁性固体，广泛存在于自然界中，在许多地质和生物过程中发挥着重要作用。它们可用作铁矿石、颜料、催化剂和热剂。氧化铁是一种无机化合物，化学式为 Fe2O3。它是铁的三大氧化物之一，其他氧化物是氧化铁（II）和氧化铁（III）。它也被称为铁锈、氧化铁或赤铁矿 rust; ferric oxide; hematite 0 Product flow 2024-04-16T19:00:21.326578+08:00 ILCD format 00.01.05 Mass 1.0
