an·ti·mo·ny

 (ăn′tə-mō′nē)
n. Symbol Sb
A metallic element having two allotropic forms: a hard, extremely brittle, lustrous, bluish-white, crystalline material and a gray amorphous form. It is used in a wide variety of alloys, especially with lead in battery plates, and in the manufacture of flame-proofing compounds, paint, semiconductor devices, and ceramic products. Atomic number 51; atomic weight 121.76; melting point 630.63°C; boiling point 1,587°C; specific gravity 6.68; valence 3, 5. See Periodic Table.

[Middle English antimonie, from Medieval Latin antimōnium, perhaps from Arabic al-'iṯmid : al-, the + 'iṯmid, antimony (perhaps from Greek stimmi; see stibine).]

an′ti·mo′ni·al adj.

antimony

(ˈæntɪmənɪ)
n
(Elements & Compounds) a toxic metallic element that exists in two allotropic forms and occurs principally in stibnite. The stable form is a brittle silvery-white crystalline metal that is added to alloys to increase their strength and hardness and is used in semiconductors. Symbol: Sb; atomic no: 51; atomic wt: 121.757; valency: 0, –3, +3, or +5; relative density: 6.691; melting pt: 630.76°C; boiling pt: 1587°C
[C15: from Medieval Latin antimōnium, of uncertain origin]
