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.
The garnet family is one of the most complex in the gem world. It is not a single species, but is composed of multiple species and varieties. [54] It is the state mineral of Connecticut, [55] New York's gemstone, [56] and star garnet (garnet with rutile asterisms) is the state gemstone of Idaho. [57]
Mangalloy, also called manganese steel or Hadfield steel, is an alloy steel containing an average of around 13% manganese. Mangalloy is known for its high impact strength and resistance to abrasion once in its work-hardened state.
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 ...
"Manganese is a mineral that is needed for one of the main antioxidant pathways in the body, which helps combat oxidative stress and inflammation, two main risk factors for heart disease and ...
In a given manganese nodule, there is one part of iron oxide for every two parts of manganese dioxide. [ 23 ] A wide range of trace elements and trace minerals are found in nodules with many of these incorporated from the seabed sediment, which itself includes particles carried as dust from all over the planet before settling to the seabed .
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 ...
Magnetite is one of the very few minerals that is ferrimagnetic; it is attracted by a magnet as shown here. Unit cell of magnetite. The gray spheres are oxygen, green are divalent iron, blue are trivalent iron. Also shown are an iron atom in an octahedral space (light blue) and another in a tetrahedral space (gray).
