Carbon is found widely in the crust of the earth and its atmosphere. Carbon plays an important role in human life. It is essential to human production.
Diamonds last forever

Diamond, the hardest substance found in nature. It is 4 times as hard as corundum.

What is the reason for diamond’s high hardness?

In the first century AD, diamond was recorded in the literature. In the 1,600 years that followed, no one knew the true composition of diamond. The “material” of diamonds was only discovered in the second half the 18th century.

French chemist Lavoisier (1743) and other scientists conducted experiments during the 70s and 90s in the 18th century on burning diamonds with oxygen. The result was carbon dioxide, which is a mixture of carbon and oxygen. substance. The carbon in this case comes from diamond. These experiments confirmed that carbon is the main component of diamond.

Although diamonds are composed of carbon, the reason for their high hardness is still unknown. Carbon is used in the production of pencil lead. But graphite has a softer mineral than human nails.

What makes diamond and graphite different?

William Bragg (1862-1942), British physicist and his son, answered this question only in 1913. Bragg (1862-1942) and his son used X rays to study diamond crystals and observe the atoms. They discovered that every carbon atom was tightly combined with four carbon atoms surrounding it to form a dense, three-dimensional structure in the diamond. This unique structure has never been observed in any other mineral. This dense structure gives diamonds a density of 3.5g/cm, about 1.5 times that of graphite. This dense structure is what gives diamonds their greatest hardness. Other words, diamonds are formed when carbon atoms are squeezed.

Synthetic diamond

It is the hardest material in nature. As such, it has many industrial applications, including fine abrasive products, high-hardness tools, different drill bits, wire drawing dies, etc. It is also used to make precision instruments.

Diamond has many other excellent physical characteristics, including super-hardness. It is called the “king” of hardness and the “king” of gems. The angle of diamonds crystals is 54deg44’8″. In the 1950s the United States successfully created synthetic diamonds by using graphite. Now, synthetic diamonds can be found in many areas of production and daily life. However, it is difficult to create large particles.

Graphite Graphite Graphite is a dark grey opaque fine-scale solid with metallic luster. It is soft with a greasy feeling and excellent electrical conductivity. Carbon atoms in the graphite have a planar, layered structure. Because the bonding is relatively weak between layers, it’s easy to separate and slide between them. Main functions: making pencils, electrodes, tram cables, etc.

Fullerene was discovered as the fourth carbon crystal in 1985. It is found after graphite, linear carbon and diamond. Fullerene was discovered as a new industrial material. Its hardness exceeds diamond and its stiffness (ductility), is superior to steel.

It’s 100 times stronger than copper. It conducts electricity better, is more conductive, and weighs only 1/6 as much.

The columnar and tubular molecules can also be called bucky tube or carbon nanotubes. C60 is aromatic, soluble with benzene and sauce red. It can be produced by resisting heating graphite or using the arc method. C60 may be a superlubricant due to its lubricity. C60 with metal doping has superconductivity. It is a promising superconducting substance. C60 is also used in many different fields, including semiconductors.
