Iron (III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It occurs in nature as the mineral hematite, which serves as the primary source of iron for the steel industry. It is also known as red iron oxide, especially when used in pigments.

Iron (III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron (II) oxide (FeO) the rarer form, and iron (II,III) oxide (Fe3O4) which naturally as magnetite.

Jul 13, 2015 · 铁（ Iron, Fe ），原子序数 26 ，原子量 55.84 ，电负性 1.8 （ 2 + ）和 1.9 （ 3 + ）。 地壳丰度 58 000 mg/kg (5.8 ％ ) ，第四位。 岩石中含铁量以超基性岩、玄武岩含铁量较高，沉积岩、花岗岩含铁量较低。 主要含铁矿物有铁盐 (FeCl 3 ) 等。 由于地壳中铁丰度较高，土壤中含铁量也较高，含量范围为 Fe 2 O 3 1 ～ 9 ％，平均 5.7 ％。 以灰化土、腐殖土含铁较低 0.35 ～ 0.59 ％。 红土含铁较高，可达 9.3 ％。 我国土壤 Fe 2 O 3 平均含量为 4.7% ，东部平原地 …

三硫化二铁是一种无机化合物，化学式：Fe2S3，分子量为207.9，是三种铁的硫化物（iron sulfide）之一，为黑色固体，常温下易转变为黄绿色。 在空气中容易被氧化，因此自然界中不存在，只能通过实验室化学方法制备。 三硫化二铁简称 硫化铁，并不能用三价铁与硫化氢反应制取，因为会发生 氧化还原反应。 但是干态的三价非离子铁并不能氧化-2价硫元素，而且在强碱性溶液中，Fe 3+ 可以与S 2- 反应生成三硫化二铁沉淀。 所以在强碱性溶液中Fe 3+ 与S 2- 相遇会 …

Fe2O3通常通过氧化铁或熔融铁和空气反应而成。 一种常见的方法是在高温下氧化铁矿石，将其转化为Fe2O3。 1、在一般使用条件下并不具有严重的安全风险。 2、它是一种刺激性粉尘，应避免吸入。 3、在处理Fe2O3时，应佩戴适当的防护措施，如口罩和手套。 4、在处理过程中应注意避免皮肤接触和吸入粉尘。 中文名:FE2O3,英文名:FE2O3,CAS:,MSDS.

Ferric oxide, also called by its IUPAC name iron Trihydrate or iron (III) oxide, is an inorganic compound represented by the chemical formula Fe 2 O 3 or Fe 2 H 6 O 3 [1, 2]. It is one of the most important oxides of iron, the other two being ferrosoferric oxide (Fe 3 O 4) and ferrous oxide (FeO) respectively [3, 4].

Fe 2 O 3 is the chemical formula of Iron (III) oxide which has three oxygen atoms, and two iron atoms. The oxidation state of Fe 2 O 3 is +3. The bond formation between oxygen and iron depends on the difference in electronegativity between these two atoms. Iron (Fe) is metal whereas oxygen (O 2) is non-metal.
