Zinc \Zinc\ (z[i^][ng]k), n. [G. zink, probably akin to zinn
tin: cf. F. zinc, from the German. Cf. {Tin}.] (Chem.)
An abundant element of the magnesium-cadmium group, extracted
principally from the minerals zinc blende, smithsonite,
calamine, and franklinite, as an easily fusible bluish white
metal, which is malleable, especially when heated. It is not
easily oxidized in moist air, and hence is used for sheeting,
coating galvanized iron, etc. It is used in making brass,
britannia, and other alloys, and is also largely consumed in
electric batteries. Symbol Zn. Atomic number 30. Atomic
weight 65.38. [Formerly written also {zink}.]
[1913 Webster]

produced by the action of methyl iodide on a zinc sodium

inflammable in the air. It has been of great importance in
the synthesis of organic compounds, and is the type of a
large series of similar compounds, as zinc ethyl, zinc
amyle, etc.

{Zinc oxide} (Chem.), the oxide of zinc, {ZnO}, forming a
light fluffy sublimate when zinc is burned; -- called also
{flowers of zinc}, {philosopher's wool}, {nihil album},
etc. The impure oxide produced by burning the metal,
roasting its ores, or in melting brass, is called also
