Hazards. Osmium tetroxide is acutely toxic. It is a severe irritant (eyes, respiratory tract) and can cause irreversible eye damage. Direct contact to the eyes may cause blindness.
What happens if you touch osmium?
Osmium tetroxide is highly volatile and penetrates skin readily, and is very toxic by inhalation, ingestion, and skin contact. Airborne low concentrations of osmium tetroxide vapor can cause lung congestion and skin or eye damage, and should therefore be used in a fume hood.
Is osmium toxic to humans?
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.
Is osmium harder than diamond?
Researchers from us-based Lawrence Livermore National Laboratory (llnl) have discovered that osmium, a metal, is harder than diamond. It withstands compression better than any other material. Osmium powder and argon were placed in the hole and subjected to very high pressure of 600,000 atmospheres.
What is the strongest thing on earth?
The World’s Strongest Stuff Diamond. Unmatched in its ability to resist being scratched, this much-loved gemstone ranks the highest in terms of hardness. Graphene. Spider silk. Carbon/carbon composite. Silicon carbide. Nickel-based super-alloys.
How do you dispose of osmium tetroxide?

What is the lightest metal on earth?
Magnesium is the lightest structural metal and abundantly available in the earth’s crust and seawater. Magnesium is the third most commonly used structural metal, following steel and aluminum.
What are 5 interesting facts about osmium?
Facts About Osmium Atomic Number: 76 Atomic Symbol: Os Atomic Weight: 190.23 Melting Point: 5,491.4 F (3,033 C) Boiling Point: 9,053.6 F (5,012 C) Word origin: Osmium comes from the Greek term osme, which means smell, scent, odor.
What’s the heaviest liquid on Earth?
Mercury is the densest liquid at standard conditions for temperature and pressure (STP). Also called quicksilver, mercury has been known for more than 3,500 years. It is an important metal in industry, but it is also toxic.
What does osmium tetroxide do to the body?
Acute/short-term: Osmium tetroxide is generally corrosive and can cause chemical burns to the skin, eyes, and respiratory tract. Acute inhalation exposure can lead to a burning sensation, tearing, cough, headache, wheezing, shortness of breath, pulmonary edema, and, ultimately, death at high concentrations.
What is the price of osmium?

Which metal has the least density?
Under standard conditions, lithium is the lightest metal and the least dense solid element. It is a soft, silver-white metal belonging to the alkali metal group of chemical elements.
How dangerous is osmium tetroxide?
Osmium tetroxide (OsO₄) is a colorless, crystalline solid or pale-yellow mass with an unpleasant, acrid, chlorine-like odor. Osmium tetroxide is highly poisonous. Exposure to osmium tetroxide may cause harm to the skin, eyes, and respiratory system. Workers may be harmed from exposure to osmium tetroxide.
Is osmium a rare metal?
Osmium is rare and has some distinctive properties that make it a fascinating element. It is plopped in the middle of the periodic table and has some mighty strange neighbors, some of which don’t really exist (1). But it also has some valuable neighbors – palladium, silver, platinum, and gold (Figure 1).
What is the hardest thing in the universe?
Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
Is osmium the strongest metal?
Osmium is the densest substance known and the hardest of all platinum group metals (PGMs). It is ten times harder than platinum itself. Osmium also has a higher melting point than the other platinum group 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. Wash hands carefully before eating, drinking, smoking, or using the toilet.
What is the rarest metal on earth?
The rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.
How strong is osmium?
Osmium (3920–4000 MPa)
Can you crush a diamond with a hammer?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure. Diamonds, because of their lack of flexibility in the structure, are not actually very strong at all.
What is the heaviest metal in the world?
Osmium is one of the heaviest materials on earth, weighing twice as much as lead per teaspoon. Osmium is a chemical element in the platinum group metals; it’s often used as alloys in electrical contacts and fountain pen nibs.
What does osmium smell like?
Osmium tetroxide has a characteristic, unpleasant, irritating odour similar to that of chlorine and ozone with a touch of garlic.
Is osmium toxic?
The metal is not toxic, but its oxide is volatile and very toxic, causing lung, skin and eye damage. Osmium occurs uncombined in nature and also in the mineral osmiridium (an alloy with iridium).
Why is osmium so expensive?
Osmium tetroxide is expensive because osmium is a rare element. Osmium is one of the rarest elements in the Earth’s crust. Osmium is obtained as a by-product from nickel and copper processing. The US production of Os is probably only about 75 kg/year.
