The hardest thing in the world, diamond is slag in front of it
What is the hardest material in the world? In fact, it is difficult to determine with the current technology of mankind. But when it comes to the hardest things in the world that humans have discovered so far, it is non-sulfided carbon alkyne. Its hardness is 200 times that of steel, 40 times that of diamonds, and twice that of graphene. Let's take a look at the extremely hard materials, such as carbon sulphide.
The hardest thing in the world, sulfurized carbon alkyne
The carbonized carbon alkyne is 200 times stronger than steel. As a very simple structure, the sulfurized carbon alkyne consists of a series of single atoms. The carbonized carbon alkyne has a tensile height three times that of diamond and a tensile strength twice that of graphene, which is extremely unstable because it is extremely unstable. According to theoretical calculations by American scientists, the one-dimensional linear band of carbon alkyne is stronger and firmer than any material. The super hardness is unprecedentedly unmatched, 40 times that of diamonds, and graphene Twice, you can safely use it to create ultra-sturdy equipment.
The hardest stone in the world, diamond
Diamonds can be said to be invincible in terms of hardness. There is nothing in real life that can scratch diamonds. This may be the reason why many people use diamonds to make rings. As a substance formed by closely arranging carbon atoms together, diamonds are commonly used for drills, saws, sandpaper, and the like. But although the diamond is very hard, it is not the strongest. With a hammer, you can gently knock the diamond into pieces.
The hardest metal in the world, chrome
Chromium is currently the hardest metal in the world, with a Mohs hardness of 9, and is the hardest metal ever detected in the universe. It is also the most dense metal known to date. For example, in the manufacture of wire cutters, military defense equipment, aircraft and other parts, the color of the common red emerald is also the product of chromium, and it is also an essential trace element of the human body.
Material hardness list:
First place: carbon sulfide alkyne (not mentioned before)
Second place: graphene
Honeycomb structure of graphene, which is the most intense of all measured materials. Graphene is composed of a single layer of carbon atoms. As a hard-to-manufacture material, in real life, graphene is used to make display screens.
Third place: hexagonal diamond
Hexagonal diamond is the hardest material found in nature. Its structure is similar to that of diamonds and is composed of carbon atoms. But unlike diamonds, hexagonal diamonds are arranged more stably than diamonds. In terms of hardness, hexagonal diamond is 58% higher than diamond.
Fourth place: wurtzite type boron nitride
As a substance very similar to the structure of diamonds, wurtzite type boron nitride is formed under high temperature and high pressure conditions during volcanic eruption, and its hardness is 18% higher than that of diamond. In daily life, wurtzite-type boron nitride is commonly used in the manufacture of various cutting tools and plays a large role in the field of materials requiring high hardness.
Fifth place: metallic glass made of palladium
A metallic glass made of a microalloy of palladium, which is not high in density and even lighter than steel. It is similar to aluminum-titanium, but the palladium-specific chemical structure can maintain the strength while counteracting the inherent brittleness of the glass. . In terms of stability, metallic glass made of palladium is also among the best.
Sixth place: maraging steel
Maraging aging generally refers to the process of producing hard tissue in steel by maraging. Steels that have undergone maraging time are called maraging steels. Maraging steels have excellent strength and toughness and are excellent in ductility. Therefore, maraging steels are commonly used in aviation, aerospace, and manufacturing molds.
Seventh place: 锇
The metal chemical element of the platinum group, ruthenium, is a very hard metal, its appearance is blue, and it is a stable crystal structure. When the base metal is used as a monomer, its hardness will be greatly improved. In daily life, enamel is commonly used in pens, electrical contacts, etc., and some metal chemical elements are used in areas that require extreme durability and hardness.
Eighth: carbon composite
There are many types of carbon composites, but almost all carbon and carbon composites have very good strength. This very lightweight material is resistant to large tensions. Carbon composites also absorb a large amount of external force before the object cracks, thus maintaining their stability. Therefore, in life, carbon composite materials are commonly used in aircraft engines, space shuttle shells and intercontinental missile tips.
