What is the hardest substance in the world? What are the areas in which it is commonly used?

The hardest substance in the world is graphene; Graphene is often used as the most ideal material for integrated circuit electronic devices, graphene can also be used as transparent conductive electrodes, thermal conductive materials, thermal interface materials, graphene transistors, etc.

Of all the materials found or created on Earth, diamonds rank seventh in hardness. While some natural (but rare) materials and synthetics have surpassed diamonds in their hardness, diamonds remain unassailable.

Diamonds are also still the most scratch-resistant material known to mankind. Not only are metals such as titanium far from diamonds compared to diamonds, but even extremely hard ceramics or carbides are not comparable to diamonds in terms of hardness or scratch resistance. Other crystals known for their hardness, such as rubies or sapphires, are not as hard as diamonds.

This substance is diamonds. Industrial sector. Security field, decoration field. The field of luxury goods is a field that is often used, and it can be used very well in these fields, and it can also give full play to the characteristics of this material.

This thing is the polymeric diamond nanorod. Abbreviated as ADNR, it is a nano-sized diamond. It is used in the industrial field, in decorations, in the field of creation, in the field of design, and also in the field of security.

The top 20 chemical elements are as follows:

Hydrogen (qīng), helium (hài), lithium (lǐ), beryllium (pí), boron (péng) carbon (tàn), nitrogen (dàn), oxygen (yǎng), fluorine (fú), neon (nǎi) sodium (nà), magnesium (měi), aluminum (lǚ), silicon (guī), phosphorus (lín) sulfur (liú), chlorine (lǜ), argon (yà), potassium (jiǎ), calcium (gài) The periodic table of chemical elements is a list of chemical elements sorted from smallest to largest according to their atomic number. The list is roughly rectangular in shape, with spaces in some element periods, so that elements with similar characteristics are grouped into the same family.

Such as alkali metal elements, alkaline earth metals, halogen elements, rare gases, etc. This results in the periodic table forming an elemental partition with seven primary families, seven secondary groups, and zero families.

Because of its ability to accurately ** the properties of various elements and the relationships between them, the periodic table is widely used in chemistry and other scientific fields as a useful framework for analyzing chemical behavior.

What is the hardest thing in the world:

1. Carpylene, carboxylene is recognized as the toughest substance in the world, its hardness is 40 times that of superdiamond, and it is 2 times the tensile strength of graphene. Carboxyne is also a carbon element, a chain formed by carbon atoms coming together. However, carboxylene has not yet been completely created, its physical properties are only the result of computer simulations, and only "products" close to carboxylene can be created in the laboratory.

About "the hardest substance on earth, the diamond cushion is not enough to see, the first place horror hard is far ahead".

2. Graphene, graphene is 20 times harder than diamond, and its birth was first separated from graphite by scientists. Graphene and diamond are both carbon elemental, with identical chemical properties, but their physical structure characteristics are very different. Graphene is used much more than diamond, and it is a waste to use it as a cutting tool, because graphene has good wire properties, thermal properties, and optical properties, graphene is considered a revolutionary material, which can be used in aerospace, batteries, biomedicine, drug delivery and other fields.

3. Diamond, it can be regarded as the hardest material on the earth, and its other identity is the original diamond that symbolizes love. Diamond is carbon elemental, and because it is too hard, the only way to cut diamond is through laser and diamond powder. Diamonds are also often used as cutting tools, such as diamonds.

However, diamond is only the hardest of the natural substances. Compared to the hardest matter on earth, the bottom of the diamond pad is not enough to see, and the first horror is far ahead.

Hello dear, it is currently recognized that the hardest substance in the world is the golden sparrow. Diamonds are formed deep underground in the earth, and they are transformed by carbon atoms through extremely high pressures and temperatures. Because of its hard texture, scratch resistance and high refractive index, it has received extensive attention and application.

However, synthetic diamond is slightly less hard than naturally occurring diamond, but it is still the hardest of the man-made materials currently recognized. Carbon-based materials such as carbon nanotubes and graphene are also very hard, and are considered one of the "hardest" substances in some applications.

Hello dear <>

The hardest substance is diamond. Diamond is the rough diamond and is a natural elemental mineral composed of the element carbon. The crystals are mostly octahedral, rhomboid, dodecahedron, and cube, and sometimes polymorphic.

Most of them are colorless and transparent, but if they contain trace elements, they will also appear in different shades such as brown, gray, and white. The crystal surface has a diamond luster, which is the strongest luster among natural colorless transparent minerals. With a hardness of 10 on the Mohs scale, it is the hardest substance naturally occurring in nature.

Relative density. Brittle and good abrasion resistance. Non-conductive.

It has good thermal conductivity, and its thermal conductivity is 5 times that of copper at room temperature. The melting point is as high as 4000 degrees Celsius, and the temperature of burning in the air is 850-1000 degrees Celsius. Hydrophobic and pro-tan pure oil.

Diamond is formed under high temperature and high pressure conditions in the deep part of the earth, and is mainly produced in kimberlite, potassium-magnesium porphyry and dolerite. Southern Africa, Russia, Australia and other places are the world's major diamond producing areas, and China's diamonds are mainly produced in Mengyin, Shandong, Wafangdian, Liaoning and the Yuanjiang River basin in Hunan. Diamond is very widely used, gem-quality diamond can be carved into diamond, the thermal conductivity and resistivity of diamond is the highest among all substances, can be used on the surface of electronic components to guess the silver nano-diamond film, can reduce the size of its heat dissipation part.

The excellent infrared penetration of diamond can be used to fabricate infrared windows for satellites and high-power lasers.
