  5. Non-ferrous metal - Wikipedia

    en.wikipedia.org/wiki/Non-ferrous_metal

    In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc). [2]

  6. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    The gram-atom is a former term for a mole of atoms, and gram-molecule for a mole of molecules. [ 7 ] Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass ( M r ). [ 8 ]

    Lithium salt or a salt such as a tetraalkylammonium chloride dissolved in LiClO 4 in an organic solvent that is a mixture of 1,2-dimethoxy ethane, 1,3-dioxolane and 2,5-dimethyloxazole as a stabilizer [28] 1.5 V Li–PbCuS Lead sulfide and copper sulfide: 1.5 V 2.2 V Li–FeS Iron sulfide: Propylene carbonate, dioxolane, dimethoxyethane: 1.5 ...

  8. Amorphous metal - Wikipedia

    en.wikipedia.org/wiki/Amorphous_metal

    The material, known as Metglas, was commercialized in the early 1980s and became used for low-loss power distribution transformers (amorphous metal transformer). Metglas-2605 is composed of 80% iron and 20% boron, has a Curie temperature of 646 K (373 °C; 703 °F) and a room temperature saturation magnetization of 1.56 teslas. [7]

  9. Relative atomic mass - Wikipedia

    en.wikipedia.org/wiki/Relative_atomic_mass

    Here the "unified atomic mass unit" refers to 1/12 of the mass of an atom of 12 C in its ground state. [13] The IUPAC definition [1] of relative atomic mass is: An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12 C.
