Carbon is found widely in the crust of the earth and its atmosphere. Carbon is essential to human life and production.
Diamonds will last forever

Diamond, the hardest substance found in nature. Its hardness exceeds that of corundum by 4 times and quartz by 8 times.

What is the reason for diamond’s high hardness?

In the 1st Century AD, diamond was first mentioned in literature. During the next 1,600-year period, however, no one knew the actual 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 diamonds burned with oxygen. The result was carbon dioxide, a mixture of carbon and oxygen. substance. The carbon in this case comes from diamond. Lastly, these experiments confirmed that the diamond material is carbon.

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.

Why are diamond and graphite different minerals?

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 diamonds, and the arrangement of atoms. They discovered that every carbon atom was tightly bonded with four surrounding carbon atoms in the crystal of diamonds, forming a dense 3-dimensional structure. 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 important uses for industry, such as fine materials, cutting tools with high hardness, different drill bits, and dies for wire drawing. It is also a component of many precision tools.

Diamond also has excellent properties like super-hardness. It is called the “king” of gems and the “king” of hardness. Diamond crystals are angled at 54deg.44’8″. The United States produced synthetic diamonds successfully in the 1950s by using graphite, a raw material. 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. The graphite atoms form a planar, layered structure. Because the bonds between layers are relatively weak, 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. It has a hardness that is higher than diamond and a degree of stiffness better than 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.
