What is the hardest material in the world?In fact, with our current technology, it's hard to know for sure.But when it comes to the world's hardest things found so far, unvulcanized carbyne is 200 times harder than steel, 40 times harder than diamond and twice as hard as graphene.Take a look at some of the hardest materials, led by carbonyl sulfide.

The hardest thing in the world, carbonyl sulfide

Carbonate sulfide is 200 times stronger than steel, and as an extremely simple substance, carbonyne sulfide consists of a string of single atoms.Carbonyl sulfide is three times as high as diamond and twice as strong as graphene, making it difficult to make because of its instability.Scientists in the United States have calculated that carbon acetylene, a one-dimensional linear band of carbon atoms, is stronger and stronger than any other material. Its unprecedented hardness is 40 times as strong as diamond and twice as strong as graphene, making it a safe place to build ultra-strong devices.

The hardest stone in the world, diamond

Diamonds are unbeatable in terms of hardness. Nothing in real life can scratch a diamond.This may be why many people use diamonds to make rings.Diamonds, made of carbon atoms packed together, are used in drills, saws and sandpaper.But diamonds, while hard, are not the strongest, and can be easily broken into pieces with a hammer.

The hardest metal in the world, chromium

Chromium is the hardest metal in the world. With a hardness of 9, chromium mohs is also the hardest metal ever detected in the entire universe. It is also the densest metal known.For instance the machine such as equipment of pliers of steel wire, military national defence USES, aircraft is made in, actually the color of common red emerald also is the product of chromium, and still be the trace element that human body needs.

Material hardness ranking:

No. 1 carbonyl sulfide

No. 2: graphene

Honeycomb structure of graphene, which is the strongest of all measured materials.Graphene is made up of a single layer of carbon atoms. It's a very difficult material to make.

No. 3： hexagonal diamond

Hexagonal diamond is the hardest material that exists in nature. Its structure is similar to that of diamond. Both of them are made of carbon atoms.But unlike diamonds, hexagonal diamonds are more stable than diamonds.In terms of hardness, hexagonal diamond is 58% higher than diamond.

No. 4: wurtzite boron nitride

Wurlitzer boron nitride, a substance with a similar structure to diamonds, was formed during volcanic eruptions at high temperatures and pressures and is 18% harder than diamonds.Wurtzite boron nitride is used in daily life to make cutting tools and is useful in areas where high hardness materials are needed.

No. 5 metallic glass made of palladium

Metallic glass, made of a microalloy of palladium, is not dense or even lighter than steel, similar to aluminum and titanium, but palladium's unique chemical structure can maintain strength while counterbalancing the inherent brittleness of glass.In terms of stability, metallic glass made of palladium is also among the best.

No. 6 martensitic aging steel

Martensite aging usually refers to the process of producing hard tissue in steel through martensite aging.Steel that has experienced martensitic aging is called martensitic aging steel.Martensitic aging steel has extremely high strength and toughness, and is very good in ductility. Therefore, martensitic aging steel is usually used in aviation, aerospace, and manufacturing molds.

Top 7: osmium

The metallic chemical element osmium of the platinum group. As a very hard metal, it has a blue appearance and a stable crystalline structure.When osmium is used as a monomer, its hardness is greatly improved.In everyday life, osmium is often used in pens, electrical contacts, and other areas where extreme durability and hardness are required.

No. 8: carbon composites

There are many different types of carbon composites, but almost all carbon and carbon composites have very good strength, this is a very light substance that can withstand a lot of tension.Carbon-composite materials can also absorb large amounts of force before they crack, thus maintaining their stability.So in real life, carbon composites are often used in aircraft engines, space shuttle casings and intercontinental missile tips.
