Chrome metal X97.5 is a hard metal of a bluish-white color. Rum is sometimes classified as a ferrous metal. This metal is capable of painting compositions in different colors, which is why it was called “chrome”, which means “paint”. Structure: Depending on the types of chemical bonds - like all metals, chromium has a metallic type of crystal lattice, that is, there are atoms in the lattice nodes metal Depending on the spatial symmetry - cubic, body-centered a = 0.28839 nm. A feature of chromium is a sharp change in its physical properties at a temperature of about 37°C. The crystal lattice of a metal consists of its ions and mobile electrons. Similarly, the chromium atom in its ground state has an electronic configuration. At 1830 °C it is possible to transform into a modification with a face-centered lattice, a = 3.69 Å. Advantages: -An absolute plus of the substance is its corrosion resistance and the ability to transfer this property to its alloys. Chrome stainless steels are of great importance because they immediately solved a number of problems in the construction of ships, submarines, building frames, and so on; Corrosion resistance is provided in another way - by covering the object with a thin layer of metal. The popularity of this method is very great; today there are at least a dozen methods of chrome plating under different conditions and to obtain different results; The chrome layer creates a bright mirror shine, so chrome plating is used not only to protect the alloy from corrosion, but also to obtain an aesthetic appearance kind. Moreover, modern chrome plating methods make it possible to create a coating on any material - not only on metal, but also on plastic and ceramics; Obtaining heat-resistant steel by adding chromium should also be considered an advantage of the substance. There are many areas where metal parts must operate at high temperatures, and iron itself does not have such resistance to stress at temperatures; -Of all refractory substances, it is the most resistant to acids and bases; An advantage of the substance is its prevalence - 0.02% in the earth's crust, and a relatively simple method of extraction and production. Of course, it requires energy, but it cannot be compared with the complex technology for producing titanium. Scope of application: For the production of stainless steel; for coating surfaces. for preserving wood and tanning leather; For dyes and pigments; for the synthesis of artificial rubies; for biological functions.
