Metal nitrided manganese Mn91N2 GOST 6008-90

Nitrided metal manganese Mn91H2 is an underestimated microelement. Description: Along with iron and its alloys, it belongs to ferrous metals. Five allotropic modifications of manganese are known: four with a cubic and one with a tetragonal crystal lattice. Manganese is found in the organisms of all plants and animals, although its content is usually very small, on the order of thousandths of a percent, it has a significant effect on life activity, that is, it is a trace element STRUCTURE: Manganese has 4 polymorphic modifications: α-Mn (body-centered cubic lattice with 58 atoms in the unit cell), β-Mn (body-centered cubic with 20 atoms per cell), γ-Mn (tetragonal with 4 atoms per cell) and δ-Mn (body-centered cubic). Transformation temperature: α=β 705 °C; β=γ 1090 °С and γ=δ 1133 °С; The α modification is fragile; γ (and partly β) is plastic, which is important when creating alloys. Properties: Silvery-white color with a slight gray coating is highlighted by manganese. It is superior to iron in hardness and brittleness. Is paramagnetic. When interacting with the air, manganese oxidizes. It is covered with an oxide film that protects it from subsequent oxidation reactions. It dissolves in water and completely absorbs hydrogen without reacting with it. When heated, it burns in oxygen. Reacts actively with chlorine and sulfur. When interacting with acidic oxidizing agents, it forms manganese salts. Density - 7200 kg/m3, melting point - 1247°C, boiling point - 2150°C. Specific heat capacity - 0.478 kJ. Has electrical conductivity. Contacting with chlorine, bromine and iodine forms dihalides. At high temperatures it interacts with nitrogen, phosphorus, silicon and boron. Reacts slowly with cold water. During heating, the reactivity of the element increases. The output produces Mn(OH)2 and hydrogen. Scope of application: in the smelting of various alloys of non-ferrous metals; for creating anti-corrosion coatings on steel, aluminum, copper and zinc; in industry, manganese compounds; in glass production; in the production of drying oils and in galvanic cells.
