The hardest substance known in nature is diamond.

Diamond is commonly known as "diamond diamond". It is a mineral composed of carbon and is an allotrope of carbon. Diamond is the hardest substance found naturally in nature.

Hardness of diamond:

According to the Mohs hardness scale, there are 10 grades, and diamond (diamond) is the highest grade 10; For example, the hardness of a knife is about 4 for copper coins, 2 to 3 for nails, and 6 for glass.

The new Mohs hardness of diamond is 15, the microhardness is 10000kg mm2, the microhardness is 1000 times higher than quartz, and 150 times higher than corundum. The hardness of diamond is directional, the hardness of the octahedral crystal plane is greater than that of the rhombic dodecahedral crystal plane, and the hardness of the rhombic dodecahedral crystal plane is greater than the hexahedral crystal plane hardness.

Diamond. Diamond is the hardest substance known in nature, with a relative hardness (Mohs scale) of 10 and a microhardness of 98,588 MPa (square cone indentation method). The absolute hardness of diamond is 1000 times that of quartz and 150 times that of corundum.

The origin, deposit, and color of diamond are different, and its hardness is different. The hardness of the same diamond is different on different crystal planes.

Diamond, also known as diamond, is a mineral composed of carbon, which makes diamond the hardest substance in nature due to its special carbon structure, but did you know? Scientists have discovered something harder than diamonds.

Nature's hardest substance, what happens to diamond when it encounters high temperatures and hammering!

However, from the perspective of the structure of matter and space, any material entity should have an internal space, and if the hardness of the substance is related to the size of the space that constitutes the substance, it should be a material entity with a small internal space that is harder. However, from the perspective of the material entity of the molecular structure on the earth, diamond is the hardest, however, diamond is not the densest substance on earth. Therefore, it seems that a single criterion does not determine that a substance is the hardest substance in the universe.

The hardest substance known to be on Earth is diamond.

It is more precious than **, it is used for precision machine tools, special guard drill bits, it is transparent throughout, through polishing, it is the most luxurious decoration on the earth, ordinary people can not afford it. Of course, there may be something harder than diamond that we have not yet discovered, and maybe in the future, science will be developed, and human beings will be able to make even harder diamonds. The hardest substance is "graphene", which is stripped from graphite and made up of carbon atoms.

It is composed of a two-dimensional crystal with the thickness of only one atom.

Although hardness and density are only disproportionately related, hardness is related to the structure of matter, and it is right that neutron star matter is the hardest, not because of the highest density, but because of the structure, strong interaction force.

It is the largest force known so far, far exceeding the electromagnetic force.

Gravitational and weak forces.

The particles are strongly connected to each other, and the natural hardness is the largest, which is the reason for the high hardness of many substances.

The density of iridium is relatively large, but it is not as large as osmium, and the hardness of iridium is relatively high, which is similar to that of some special steels.

It was comparable, but was far worse than chromium. Osmium density is the boss in metal, and chromium hardness is the boss. I don't know how his theory of high density and hard work came about, like gold and platinum are very dense but very soft.

I guess the author copied it somewhere. Now the hardest in nature is diamond, far more than other substances. And there will be differences in the density of different diamonds, for example, the hardness of black diamonds is less than that of white transparent diamonds, which is obvious.

It should be said that diamonds, because diamonds are the most stable structure, and they are also very hard, the hardest in the world.

It should be a diamond, which is very hard and has been formed by natural changes over a very long period of time.

The hardest substance known in nature is actually diamond, also known as diamond. Diamond is a very sharp substance, and this substance is an allotrope of carbon, yet it is the hardest known object found by humans on Earth. So now many people like to use diamond rings when they get married, because diamonds can represent a kind of purity, represent the indestructibility of love, and have a very beautiful symbolic meaning.

The so-called diamond is actually a kind of diamond that has been artificially processed, diamond is a natural mineral, and the distribution of molecular structure is very regular, so the hardness of diamond is the strongest hardness known to human beings on the earth. To put it simply, diamond is an elemental crystal composed of carbon elements formed under high pressure and high temperature conditions in the deep part of the earth. And it is precisely because the strength and stiffness of the diamond are relatively large, and at the same time transparent, and the diamond is very rare, so this material represents a symbol of eternity, representing eternal love.

Diamonds are the hardest of all natural minerals and are so brittle that they will break if you touch them too hard. In ancient times, diamonds have become recognized as the king of gemstones, so diamonds are very expensive in the current market, and they are calculated according to how much money is a carat. But diamonds have this characteristic, that is, the bigger the diamond, the more expensive they are sold for, and the value per carat is very high, because the bigger the diamond, the rarer it is in the world.

In general, the hardest known substance in the world is diamond, which is often referred to as diamond, which is a natural mineral and a component of carbon, because diamond is extremely hard, transparent and clear, so it is often called a symbol of love for life, until death. The chemical composition of diamond is carbon, which is the only one in gemstones that is composed of a single element, which belongs to the equiaxed crystal system. The presence of the most common impurities, the most important of which are N and B, is related to the type and nature of the diamond.

The crystal morphology is mostly octahedral, rhomboid, dodecahedron, tetrahedron and their aggregates.

The hardest substance known in nature is carboxylene.

In ancient times, it was believed that stones were the hardest things, so our ancestors would pick them up from the ground and throw them at our prey. Sure enough, the animals hit by the stones either bleed from the head or died on the spot. This is the first time that humans have compared hardness in nature.

Later, human beings had their own civilization, mastered the smelting technology of metal, and created the earliest metal in human history, that is, bronze. Bronze was believed to be a harder substance than rock, as a chisel made of bronze could be used to cut through rocks and build roads. Later, people found a harder material than bronze, and that was steel.

But it soon became clear that the hardness of non-metallic materials is the real potential.

The carbon atoms in caryne are joined together by double bonds or alternating single and triple bonds. Caryne is the toughest substance in the world, it is more than 200 times harder than steel, 40 times harder than diamond, and twice as hard as graphene. Caryne will become the main component of ultra-high power devices in the future.

Caryne is harder than the hardest known materials, with carbon nanotubes and graphene reaching a hardness of Newton-metre kilograms, while carbonylene can reach 109 Newton-metre kilograms.

The strength of caryne is incomparable, and in order to break its single chain, an external force of 10 nanoN must be applied. If it is converted into energy, it can reach Newton-meter kg, which is much higher than graphene to Newton-meter kg, while carbon nanotubes are to Newton-meter kg and diamond is to Newton-meter kg.

Scientists still believe that caryne is very unstable, and some chemists insist that as long as two carbyne chains come into contact, they produce **. However, as a "famous family" of the carbon family, carbonyne still attracts many scientists.

The hardest known substance is diamond, which has the highest hardness and is composed of carbon, which can make many hard substances.

The hardest substance that occurs naturally is diamond. Diamond is a natural mineral composed of the element carbon and one of the hardest materials on earth. Its hardness reaches 10 on the Mohs scale, the highest of all minerals.

Compared with other materials, the hardness of diamond is mainly due to the special properties of its molecular structure. The carbon atoms in diamond are arranged in a crystalline structure, forming very hard crystalline bonds. This special structure gives diamond its high hardness and strength, making it an important material for many high-end industrial and scientific fields.

In addition to diamond, there are other materials that also have high hardness, such as corundum, which is the second hardest on the Mohs scale, which is rated 9, and garnet, which is the third on the Mohs scale. However, they are slightly less hard and stronger than diamonds. Qing Qingxian.
