Health effects of osmium
Osmium tetroxide, OsO4, is highly toxic. Concentrations in air as low as 10–7 g m–3 can cause lung congestion, skin damage, and severe eye damage. The oxide, in particular, should only ever be handled by a properly qualified chemist.
Is osmium the rarest metal?
Osmium is the rarest of the stable elements: its average abundance in the Earth’s crust is about 1 gram per 200 tonnes. Today, osmium is obtained commercially as a by-product of refining nickel and some of the more common platinum-group metals.
Where can you find osmium?
Osmium occurs in iridosule and in platinum-bearing river sands in the Urals, North America, and South America. It is also found in the nickel-bearing ores of Sudbury, Ontario region along with other platinum metals.
Can you eat osmium?
* Do not eat, smoke, or drink where Osmium Tetroxide is handled, processed, or stored, since the chemical can be swallowed.
Can you melt osmium?
Osmium is unworkable as a metal. It cannot be melted and shaped like most metals. Because it is unworkable, it has very few practical uses.
What can dissolve osmium?
Osmium can be dissolved by acids or aqua regia only if exposed to these liquids for a long period. The metal reacts with oxygen to form osmium tetroxide (OsO4) after heating. Osmium tetroxide is highly toxic and the only essential commercial compound of osmium.
Does osmium conduct electricity?
Osmium (Os): As the densest and hardest of the group, osmium is often alloyed with other PGMs such as platinum and iridium. Osmium also is an excellent conductor of electricity and an effective oxidation catalyst.
What is the price of osmium?
$400 per troy ounce
Its atomic number is 76, and its atomic weight is 190.23. As of 2018, it sells for $400 per troy ounce (about 31.1 grams), and that price had held steady for more than two decades, according to Engelhard Industrial Bullion prices.
At what temperature does osmium oxidize?
Osmium will react at 200° C with air or oxygen to form OsO4. Osmium exhibits oxidation states from 0 to +8 in its compounds, with the exception of +1; well-characterized and stable compounds contain the element in +2, +3, +4, +6, and +8 states.
How is osmium purified?
The material started with was a comparatively pure sample of the best known salt containing osmium, potassium osmate, K. OsO. ^2H20. This salt was further purified by distillation with nitric acid or aqua regia and absorption of the liberated tetroxide vapors in a solution of caustic potash.
What is the heaviest metal?
osmium
The Heaviest Metal. The heaviest metal is osmium, which has, bulk for bulk, nearly twice the weight of lead. The specific gravity of gold is about 19 1/4, while that of osmium is almost 22 1/2.
How is osmium brittle?
Osmium Basic Facts
Properties: Osmium has a melting point of 3045 +/- 30 °C, boiling point of 5027 +/- 100°C, specific gravity of 22.57, with a valence usually +3, +4, +6, or +8, but sometimes 0, +1, +2, +5, +7. It is a lustrous blue-white metal. It is very hard and remains brittle even at high temperatures.
