The hardest thing on earth, a natural substance

Diamond, commonly known as "diamond diamond". It is customary to refer to the processed diamond as the diamond and the unworked as the diamond. In China, the name diamond was first found in Buddhist scriptures.

Diamond is the hardest substance in nature, and the best color is colorless, but there are also special colors, such as blue, purple, golden yellow, etc. These colored diamonds are rare and are among the treasures of diamonds. India is a famous diamond producing country in history, and many famous diamonds such as "Koh-i-i-Noor", "Prince Regent", "Orlov" are from India.

Diamonds are produced in very small quantities, usually one billionth of a billion mined and therefore very expensive. Diamonds that have been polished are generally round, rectangular, square, oval, heart-shaped, pear-shaped, marquise-shaped, etc. The heaviest diamond in the world is the "Cullinan" produced in South Africa in 1905, weighing 3,106 carats, which has been ground into 9 small diamonds, of which the diamond weight of the Cullinan No. 1, known as the "Star of Africa", still ranks first among the world's famous diamonds.

Diamond The mineral name of a diamond is diamond, and people generally call a diamond that has been sharpened a diamond. The chemical composition of diamond is pure carbon, with a hardness of 10, which is the hardest substance in nature, with a specific gravity to, refractive index. Brittle, transparent, not afraid of strong acids and alkalis.

Recently I heard that graphene is the hardest.

Chromium. The hardness of chromium and diamond is equal and both are hard.

Diamonds, of course.

The hardest substance in the world is carboxylene.

A caryne is a chain of carbon atoms that are held together by double or alternating single and triple bonds. Caryne is considered the strongest material in the world, with more than 200 times stronger than steel, 40 times stronger than diamond, and twice the tensile strength of graphene. Caryne will have an important use in the development of ultra-high-strength equipment in the future.

Textbooks are diamonds.

See this report:

Two Chinese-American scientists at Columbia University in the United States recently found that a two-dimensional carbon atom crystal called graphene in pencil graphite is harder than diamond and 100 times stronger than the world's best steel. The graphite in the pencil is formed by the lamination of countless thin sheets of "graphene" with only the thickness of carbon atoms, which is a single-layer carbon atom surface material stripped from graphite materials, which is a two-dimensional structure of carbon. Since the discovery of graphene in 2004, scientific research has never stopped.

However, it was only recently that American scientists confirmed for the first time the long-held suspicion that graphene is the strongest material known in the world! This astonishing scientific discovery was made by two Chinese-American scientists at Columbia University, Li Chenggu and Wei Xiaoding. Not only can this substance be used to develop and manufacture paper-thin materials for ultralight aircraft, to make ultra-tough body armor, but it has even opened the door to the manufacture of ultra-tough cables for "space elevators", which could make the 23,000-mile-long space elevator that scientists dream of a reality in the near future!

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.

The hardest substance that occurs naturally is diamonds. According to the Mohs hardness scale, there are 10 grades, and diamond (diamond) is the highest grade 10.

Diamond refers to polished diamond, which is a natural mineral that is the rough of diamonds. To put it simply, diamond is an elemental crystal composed of carbon that is formed under high pressure and high temperature conditions in the deep part of the earth.

1.The mineral name is diamond, which is derived from the ancient Greek word adamant, which means hard and inviolable substance, and is recognized as the king of gemstones. The chemical composition of the diamond is carbon.

In other words, diamond is actually a fairly dense carbon crystal.

2.Diamond's Mohs hardness: 10, which is the highest hardness among natural minerals. But don't think that a diamond will never break if it is hard. In fact, diamonds are also quite brittle, and they will still shatter if they are hit hard.

Round, oval, marquise, heart, pear, square, triangular and cyclional. Round diamonds are the most common shape.

4.Diamonds are natural minerals. The main sources of diamonds are Australia, South Africa, and India; The United States, India, Israel, and Belgium are the bases for diamond processing and cutting. Belgium, in particular, is globally recognized as a centre for diamonds.

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.
