cobalt (redirected from cobalt nutritional deficiency)

co·balt  (kbôlt)

n. Symbol Co

A hard, brittle metallic element, found associated with nickel, silver, lead, copper, and iron ores and resembling nickel and iron in appearance. It is used chiefly for magnetic alloys, high-temperature alloys, and in the form of its salts for blue glass and ceramic pigments. Atomic number 27; atomic weight 58.9332; melting point 1,495°C; boiling point 2,900°C; specific gravity 8.9; valence 2, 3. See Table at element.

cobalt [ˈkəʊbɔːlt]

n

(Chemistry / Elements & Compounds) a brittle hard silvery-white element that is a ferromagnetic metal: occurs principally in cobaltite and smaltite and is widely used in alloys. The radioisotope cobalt-60, with a half-life of 5.3 years, is used in radiotherapy and as a tracer. Symbol: Co; atomic no.: 27; atomic wt.: 58.93320; valency: 2 or 3; relative density: 8.9; melting pt.: 1495°C; boiling pt.: 2928°C

[German Kobalt, from Middle High German kobolt goblin; from the miners' belief that malicious goblins placed it in the silver ore]
