How is magnetic paint made?

Answer 1

A metal (Ancient Greek métallon, μέταλλον) is an element, compound, or alloy characterized by high electrical conductivity

Metals are usually inclined to form cations through electron loss,[1] reacting with oxygen in the air to form oxides over changing timescales (iron rusts over years, while potassium burns in seconds). Examples: 4 Na + O2 → 2 Na2O (sodium oxide)2 Ca + O2 → 2 CaO (calcium oxide)4 Al + 3 O2 → 2 Al2O3 (aluminum oxideMetals are often extracted from the Earth by means of mining, resulting in ores that are relatively rich sources of the requisite elements. Ore is located by prospecting techniques, followed by the exploration and examination of deposits. Mineral sources are generally divided into surface mines, which are mined by excavation using heavy equipment, and subsurface mines.

Once the ore is mined, the metals must be extracted, usually by chemical or electrolytic reduction. Pyrometallurgy uses high temperatures to convert ore into raw metals, while hydrometallurgy employs aqueous chemistry for the same purpose. The methods used depend on the metal and their contaminants. When a metal ore is an ionic compound of that metal and a non-metal, the ore must usually be smelted - heated with a reducing agent - to extract the pure metal. Many common metals, such as iron, are smelted using carbon as a reducing agent. Some metals, such as aluminum and sodium, have no commercially practical reducing agent, and are extracted using electrolysis instead. Sulfide ores are not reduced directly to the metal but are roasted in air to convert them to oxides.

Answer 2

1) Melt the metal

2) poured into a rectangular mold

3) rectangular block cooled and taken out

4) put through a press and it may be necessary to anneal to soften

5) Get the desired thickness

Answer 3

If I understand the question correctly, currentcosmological theory says that metal is not made in the ground, the only place atoms as large as metals can be made is the fusion process in the centers of the bigger stars. In our Earth's liquid core the metals that are already here can be mixed or separated and later deposited on or near the surface where we can get to them. Before the Earth was formed (according to these theories) all the metal and rock was floating in space, the local contraction started, the clumps in our immediate vicinity stuck together and formed the Earth. Since then, the only metals introduced into our closed system are from small meteorites that land here fairly often. If, however, you mean how is metal "mined from" the ground, there are several different methods depending on the metal. Some of the common processes to most methods are: digging it out of the rock, crushing the rock, separating the metal. Each of these has many variations because of the differences in physical properties of each metal. For more information, each metal would probably be best asked as a separate question.

Answer 4

First the metal's ore is crushed. Then the crushed ore is mixed with coke, a , mineral, after they are mixed together, they are heated from a distance, from the fire, the person smelting the metal takes the metal that is now an actual metal bar, and that is how metal is made.

Answer 5

A single metal is a crystal, where atoms are ordered on macroscopic distances in a periodic structures. Naturally different metals have different crystal structures. When different metals are melted, mixed while in liquid form an then solidified again a perfect crystal cannot be formed.

On the other hand both metals tends to form metal bond between atoms sharing electrons on large distances, so that chemical bonds form among different atoms.

Thus an alloy is strictly speaking a solution between two solids, having generally physical properties that are different from those of the individual components. The most known example is steel, an alloy between iron and carbon (that is present in a quantity between 0.02% and 2.2%).

An alloy tends to resemble under a crystal point of view to the most abundant element (steel has a crystal structure similar to iron). The atoms of the less abundant element can be distributed in different ways:

- in the interstices of the crystal;

- in substitution of atoms at the main crystal nodes

- in a combination of the above

the alloy characteristics heavily depends on the way the alloy atoms preferably distributes.

Imperfect alloys also exist, where the two metals are not completely soluble (under a solid point of view). In this case bonds between different atoms are not so frequent and different phases are present in the alloy: that is it is formed by an alternation of microscopic zones where only one of the two components is present. While perfect alloys behave mainly like crystals, imperfect alloys behave mainly like amorphous materials.

Answer 6

Metals are elements. Sometimes different metals are mixed together to form metallic alloys, such as brass.

Answer 7

When electricity pass through the metal a magnetic field is created and at that time metal made a magnet and attract all iron object

Answer 8

it is made by something. who knows..............

Answer 9

An electrical current is ran through it.
