(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.
Is there anything harder than diamond?
Diamonds remain the most scratch-resistant material known to humanity. … 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.
What is the strongest substance in the world?
Graphene. Topping the list, graphene is the strongest materials known to humans. The transparent material is composed of a single layer carbon atom arranged in a triangular lattice and it’s the basic structural element in charcoal, graphite and carbon nanotubes.
Can you break 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. … This makes the diamond incredibly hard and is why it is able to scratch any other material.
What happens if you melt a diamond?
At ~700 degrees Fahrenheit the diamond will start burning. This will produce Carbon Dioxide and change the structure so that it is no longer a diamond. As diamond is made of Carbon, it would revert back to that form while losing its mass to the production of CO2. This is due to the presence of Oxygen.
What is the toughest metal on earth?
In terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
Is Bedrock harder than diamond?
The reason diamond is so hard has to do with the arrangements of carbon atoms in its crystalline form, which has a very high packing factor. Bedrock can be made from many different substances, with a hardness anywhere from 1 to 9. So even the hardest bedrock is still not as hard as diamond.
What is the strongest animal on earth?

Can a diamond stop a bullet?
Pound for pound, diamonds are not very good at stopping bullets. The energy absorbed by diamond shattering is much less than the energy absorbed by metals deforming. A plate of steel would be better at stopping bullets than a plate of diamond.
Are Diamonds bulletproof?
It doesn’t seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world’s hardest natural material. Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.
How do you destroy a diamond?
How to Destroy a Diamond
- Smashing. Diamonds are one of the hardest gems, making them hard to cut, but they’re very fragile! …
- Oxygen. If you heat a diamond to 700 degrees Celsius in open air it will burn, because diamonds are made of carbon. …
- Fire. …
- Cleavage Planes.

What can melt a diamond?
Despite this, scientists found a way to melt diamond. Using super-strong magnetic fields, they fired small plates at 34 kilometres (21 miles) per second towards tiny pieces of the mineral, subjecting them to 10 million times normal atmospheric pressure.
What is the hardest thing to melt?
Tungsten is known as one of the toughest things found in nature. It is super dense and almost impossible to melt. Pure tungsten is a silver-white metal and when made into a fine powder can be combustible and can spontaneously ignite.
Do diamonds melt in lava?
According to Wikipedia, the temperature of lava is between 700 and 1200 °C (973 to 1473 K). The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond. … A diamond is carbon and will burn just like charcoal.
