Uses and related properties of iron, what are the properties of iron

Physical. Appearance and shape: Pure iron is a metal crystal with a silvery-white metallic luster, usually gray to gray-black high-purity iron wire color amorphous fine grains or powders.

High-purity iron wire. It has good ductility, electrical and thermal conductivity.

It is very ferromagnetic and belongs to magnetic materials.

Density : g cm3

The specific heat capacity is 460J (kg·).

The propagation rate of sound in iron: 5120m s.

Pure iron is soft, but if it is an alloy of iron with other metals or iron mixed with impurities, the melting point is usually lower and the hardness increases.

Crystal structure: face-centered cubic and body-centered cubic.

Chemical properties. Iron is an indispensable metal in the industrial sector. Iron is alloyed with a small amount of carbon - steel, which is not easy to demagnetize after magnetization, and is an excellent hard magnetic material, but also an important industrial material, and is also used as the main raw material for artificial magnetism.

Iron has a variety of allotropic forms.

Iron is a relatively reactive metal, ranking ahead of hydrogen in the metal activity order table, and its chemical properties are relatively active, so it is a good reducing agent. Iron does not burn in air, but it can burn violently in oxygen.

Iron is a valence element, 0 valence is only reducing, +6 valence is only oxidizing, +2, +3 valence is both reducing and oxidizing. In the displacement reaction, +2 valence is generally displayed, but there are a few +3 valence, such as ferrous bromide and excess chlorine reaction, oxygen reaction, acid reaction, salt reaction and so on.

Use. 1.It is used in pharmaceuticals, pesticides, powder metallurgy, hot hydrogen generators, gel propellants, combustion active agents, catalysts, water cleaning adsorbents, sintering active agents, powder metallurgy products, various mechanical parts products, cemented carbide material products, etc.

2..Pure iron is used to make the cores of generators and electric motors, reduced iron powder is used in powder metallurgy, and steel is used to make machines and tools. In addition, iron and its compounds are also used in the manufacture of magnets, medicines, inks, pigments, abrasives, etc.

3.used as a reducing agent. It is used in the preparation of iron salts. It is also used in the preparation of electronic components.

4.Used as a nutritional supplement (iron fortifier).

5.It is used as a filler for epoxy adhesives in adhesives and formulates casting repair adhesives. It is often used as a reducing agent.

It has a wide range of uses in the electronics industry, powder metallurgy, and machinery industry. It is mainly used for oil-impregnated bearings. It is mainly used for medium and low density mechanical parts.

It is mainly used for high-density mechanical parts.

The properties of iron are as follows:

1) The physical properties of iron, pure iron has a silvery-white metallic luster; It has good ductility, electrical and thermal conductivity. The density is gram cm; The melting point is 1535 and the boiling point is 2750.

2) The chemical properties of iron, iron burns 3Fe + 2O2 = Fe3O42 in oxygen; Iron reacts with acid, hydrochloric acid reacts with iron Fe 2HCl FeCl2 H2 ; Reaction of sulfuric acid with ironFe H2SO4 FeSO4 H2 Contanling 3; Reaction of iron with copper sulfate Fe CuSO4 FeSO4 Saedin Cu.

Extended information: Iron is widely distributed in life, and the content of the earth's crust is second only to oxygen, silicon, and aluminum, ranking fourth in the earth's crust. Pure iron is a flexible and malleable silvery-white metal, which is used to make the iron core of generators and motors, and iron and its compounds are also used to make magnets, drugs, inks, pigments, abrasives, etc.

It is one of the so-called "ferrous metals" in the industry (the other two are chromium and manganese) (in fact, pure pig iron is silvery-white, and iron is called "ferrous metal" because the surface of iron is often covered with a protective film of black ferric tetroxide). In addition, the human body also contains iron, and +2-valent ferrous ions are an important component of hemoglobin and are used for oxygen transport. The main iron ores used are:

Fe2O3 (hematite), Fe3O4 (magnetite), FeCO3 (siderite), etc.

Uses: Iron plays a very important role in people's daily life.

The use of pure iron--- electrical pure iron is widely used in electronic and electrical engineering, electrical components, magnetic materials, amorphous products, relays, sensors, automotive brakes, textile machinery, electric meters, solenoid valves and other products.

Its greatest use is for steelmaking; It is also used in large quantities to make cast iron and calcined iron. Iron and its compounds are also used as magnets, dyes (inks, cyanotype drawings, rouge pigments) and abrasives (red iron powder).Reduced iron powder is used in large quantities in metallurgy.

Iron is mainly smelted in iron ore, and the main component of iron ore is ferric oxide.
