zinc

A bluish-white, lustrous metallic element that is brittle at room temperature but malleable with heating. It is used to form a wide variety of alloys including brass, bronze, various solders, and nickel silver, in galvanizing iron and other metals, for electric fuses, anodes, meter cases and batteries, and in roofing, gutters, and various household objects. US pennies minted after 1982 consist of a copper-clad zinc core. Atomic number 30; atomic weight 65.38; melting point 419.53°C; boiling point 907°C; specific gravity 7.134 (at 25°C); valence 2. cross-reference: Periodic Table.

To coat or treat with zinc; galvanize.

To coat or cover with zinc.

The zinc element of a galvanic cell, prepared of proper shape and size, and often fitted with a binding-screw, ready for use.

Chemical symbol, Zn; atomic weight, 64.9. One of the useful metals, more tenacious than lead and tin, but malleable only at a temperature between 200° and 250° F.

To coat with zinc; to galvanize.

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.

zinc chloride, ZnCl2, a deliquescent white waxy or oily substance.

See Zinc oxide, below.

a white amorphous substance, Zn(NH2)2, obtained by the action of ammonia on zinc ethyl; — called also zinc amide.
