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]

an·ti·mo·ny

(ăn′tə-mō′nē)
Symbol Sb A metallic element having many forms, the most common of which is a hard, very brittle, shiny, blue-white crystal. It is used in a wide variety of alloys, especially with lead in car batteries, and in making flameproofing compounds. Atomic number 51. See Periodic Table.

Gwillim (1900) notes that the Engineer orebody "carries values in free gold, also some stibnite." However, no Engineer mine stibnite specimens are currently known, and it is suggested that the usage of "stibnite" may be synonymous with "antimony (stibnium)." Most of the work done at the time would have been in the allemontite-rich upper levels, and this source of antimony would have been the most obvious.
