What’s the hardest thing on earth?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.
But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond..
Can anything melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
Which metal lasts the longest?
Gold is clearly the most durable, but many objects fashioned from silver, copper, bronze, iron, lead, and tin have survived for several thousand years.
Is graphene harder than diamond?
But the atoms within those layers are very tightly bonded so, like carbon nanotubes (and unlike graphite), graphene is super-strong—even stronger than diamond! Graphene is believed to be the strongest material yet discovered, some 200 times stronger than steel.
Why is a diamond so strong?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
What is the weakest thing in the universe?
Gravitational forceGravitational force, the weakest of the four forces, has a strength of 10 to the minus 40, relative to electromagnetism. The force of gravity (along with electromagnetism) has a range of infinity – every single atom in the universe is ‘gravitationally aware’ of every other atom.
Can water cut diamonds?
Examples of materials that cannot be cut with a water jet are tempered glass and diamonds.
What is the sharpest blade on earth?
Since obsidian will fracture down to a single atom, it is claimed to have a cutting edge five hundred times sharper than the sharpest steel blade, and under a high magnification microscope an obsidian blade still appears smooth, whereas a steel blade has a saw like edge.
What is the hardest alloy in the world?
Stainless steel is a corrosion-resistant alloy of steel, chrome and manganese with a yield point of up to 1,560 MPa and tensile strength of up to 1,600 MPa. Just like every other steel, this alloy boasts high resistance to impact and places in the middle of the Mohs hardness scale.
What was the sharpest sword ever made?
Damascus swordsNanotech Used 2000 Years Ago to Make History’s Sharpest Swords. Damascus swords — sharp enough to slice a falling piece of silk in half, strong enough to split stones without dulling — owe their legendary qualities to carbon nanotubes, says chemist and Nobel laureate Robert Curl.
What is the strongest material on earth 2020?
The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.

Is Obsidian stronger than diamond?
Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts. … Obsidian is found all over the world.
Can Obsidian cut through diamond?
At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge. When you consider that most household razor blades are 300 to 600 angstroms, obsidian can still cut it with the sharpest materials nanotechnology can produce.
What can cut diamond?
Cleaving or sawing Diamond manufacturers cut a groove in the diamond with a laser or saw, and then split the diamond with a steel blade. Sawing is the use of a diamond saw or laser to cut the diamond rough into separate pieces.
What is the hardest stone known to man?
What Are the Hardest and Softest Minerals on the Mohs Scale? The hardest mineral on the Mohs scale is diamond, which ranks at a 10. On the other hand, the softest is talc, which ranks at a 1. Falling closely behind diamonds on the Mohs scale are corundum (9), titanium (9) and topaz (8).
What is the sharpest natural thing in the world?
The sharpest object ever made is a tungsten needle that tapers down to the thickness of a single atom. It was manufactured by placing a narrow tungsten wire in an atmosphere of nitrogen and exposing it to a strong electric field in a device called a field ion microscope.
What is the most resistant material?
Researchers have discovered that tantalum carbide and hafnium carbide materials can withstand scorching temperatures of nearly 4000 degrees Celsius.
What is the strongest rock in the world?
Diamond is the hardest known mineral, Mohs’ 10. Notes: It must be noted that Mohs’ scale is arbitrary and non-linear, i.e. the steps between relative hardness values are not necessarily equal.
Is Titanium stronger than diamond?
Titanium is not stronger than a diamond. In terms of hardness, Titanium is not harder than a diamond either. … The only advantage titanium has over steel is that it is a much lighter material. When compared to diamond, however, titanium does not come close in strength or hardness.
What is the weakest element?
For the weakest element, I would probably go for helium – one of the noble gases. It is very light and unreactive.
Can you break a diamond with a hammer?
To say something is “hard” is not the same as saying it is “strong”. 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. … This makes the diamond incredibly hard and is why it is able to scratch any other material.
Is Diamond The only thing that can cut glass?
Yes, diamonds (diamond is a 10 on the Mohs scale of hardness) can cut glass (glass is a 6 – 7 on the Mohs scale). In fact, anything harder and more durable than glass can cut glass. It’s just the law of nature and physics.
