os·mi·um

 (ŏz′mē-əm)
n. Symbol Os
A bluish-white, hard, brittle and extremely dense metallic element, found in small amounts in osmiridium, nickel, and platinum ores. It is used as a platinum hardener and in making pen points, phonograph needles, instrument pivots, and other wear-resistant items. Atomic number 76; atomic weight 190.2; melting point 3,033°C; boiling point 5,012°C; specific gravity 22.587; valence 2, 3, 4, 6, 8. See Periodic Table.

[From Greek osmē, smell (from the strong odor of osmium tetroxide).]

osmium

(ˈɒzmɪəm)
n
(Elements & Compounds) a very hard brittle bluish-white metal occurring with platinum and alloyed with iridium in osmiridium: used to produce platinum alloys, mainly for pen tips and instrument pivots, as a catalyst, and in electric-light filaments. Symbol: Os; atomic no: 76; atomic wt: 190.2; valency: 0 to 8; relative density: 22.57; melting pt: 3033±30°C; boiling pt: 5012±100°C
[C19: from Greek osmē smell, so called from its penetrating odour]

os•mi•um

(ˈɒz mi əm)

n.
