  2. Metallic mean - Wikipedia

    en.wikipedia.org/wiki/Metallic_mean

    The metallic mean (also metallic ratio, metallic constant, or noble mean [1]) of a natural number n is a positive real number, denoted here , that satisfies the following equivalent characterizations:

  3. Metal - Wikipedia

    en.wikipedia.org/wiki/Metal

    A metallic glass (also known as an amorphous or glassy metal) is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Most pure and alloyed metals, in their solid state, have atoms arranged in a highly ordered crystalline structure.

    en.wikipedia.org/wiki/Glossary_of_chemistry_terms

    This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...

    Metallic bonding, type of chemical bonding; Metallicity, in astronomy the proportion of elements other than helium and hydrogen in an object; Metallic color, a color that gives the appearance of metal; Metallic dragon, a classification of dragon found in the role playing game Dungeons & Dragons; Metallic paint, paint that provides the ...

  6. Metallicity - Wikipedia

    en.wikipedia.org/wiki/Metallicity

    This word-use is distinct from the conventional chemical or physical definition of a metal as an electrically conducting solid. Stars and nebulae with relatively high abundances of heavier elements are called "metal-rich" when discussing metallicity, even though many of those elements are called nonmetals in chemistry.

  7. Lustre (mineralogy) - Wikipedia

    en.wikipedia.org/wiki/Lustre_(mineralogy)

    A range of terms are used to describe lustre, such as earthy, metallic, greasy, and silky. Similarly, the term vitreous (derived from the Latin for glass, vitrum) refers to a glassy lustre. A list of these terms is given below. Lustre varies over a wide continuum, and so there are no rigid boundaries between the different types of lustre.

  8. Materials science - Wikipedia

    en.wikipedia.org/wiki/Materials_science

    Biomaterials science encompasses elements of medicine, biology, chemistry, tissue engineering, and materials science. Biomaterials can be derived either from nature or synthesized in a laboratory using a variety of chemical approaches using metallic components, polymers , bioceramics , or composite materials .

  9. Solid solution - Wikipedia

    en.wikipedia.org/wiki/Solid_solution

    The IUPAC definition of a solid solution is a "solid in which components are compatible and form a unique phase". [3]The definition "crystal containing a second constituent which fits into and is distributed in the lattice of the host crystal" given in refs., [4] [5] is not general and, thus, is not recommended.
