Manganese is a chemical element; it has symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Manganese (II) chloride is the di chloride salt of manganese, MnCl 2. This inorganic chemical exists in the anhydrous form, as well as the di hydrate (MnCl 2 ·2H 2 O) and tetrahydrate (MnCl 2 ·4H 2 O), with the tetrahydrate being the most common form. Like many Mn (II) species, these salts are pink, with the paleness of the color being ...
Ferromanganese. Ferromanganese metal, note mirror-like sheen responsible for German name spiegel. Ferromanganese is an alloy of iron and manganese, with other elements such as silicon, carbon, sulfur, nitrogen and phosphorus. [ 1 ] The primary use of ferromanganese is as a type of processed manganese source to add to different types of steel ...
Refractory. Refractory bricks in a torpedo car used for hauling molten iron. In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. [1] They are inorganic, non-metallic compounds that may be porous or ...
Group 7, numbered by IUPAC nomenclature, is a group of elements in the periodic table. It contains manganese (Mn), technetium (Tc), rhenium (Re) and bohrium (Bh). This group lies in the d-block of the periodic table, and are hence transition metals. This group is sometimes called the manganese group or manganese family after its lightest member ...
YInMn Blue (/jɪnmɪn/; for the chemical symbols Y for yttrium, In for indium, and Mn for manganese), also known as Oregon Blue or Mas Blue, is an inorganic blue pigment that was discovered by Mas Subramanian and his (then) graduate student, Andrew Smith, at Oregon State University in 2009. [ 1 ][ 3 ] The pigment is noteworthy for its vibrant ...
Although manganese(III) triacetate has not been reported, salts of basic manganese(III) acetate are well characterized. Basic manganese acetate adopts the structure reminiscent of those of basic chromium acetate and basic iron acetate. The formula is [Mn 3 O(O 2 CCH 3) 6 L n]X where L is a ligand and X is an anion. The salt [Mn 3 O(O 2 CCH 3) 6 ...
Manganese (II) sulfate usually refers to the inorganic compound with the formula MnSO 4 ·H 2 O. This pale pink deliquescent solid is a commercially significant manganese (II) salt. Approximately 260,000 tonnes of manganese (II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds.
