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

Diamond, the hardest substance found in nature. Its hardness measures 4 times as much as corundum, and 8 times more than quartz.

What is the reason for diamond’s high hardness?

In the 1st Century AD, diamond was first mentioned in 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. Carbon here is 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.

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 studied diamonds with X rays. They discovered that every carbon atom was tightly combined 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 minerals. 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 is widely used in industry for a variety of purposes. It is also used to make precision instruments.

Diamond also has excellent properties like super-hardness. It is called the “king” of gems and the “king” of hardness. The angle of diamonds crystals is 54deg44’8″. In the 1950s the United States used graphite to produce synthetic diamonds at high temperatures and pressure. Now, synthetic diamonds can be found in many areas of production and daily life. However, it is difficult to create large diamond particles.

Graphite Graphite Graphite is a dark grey opaque fine-scale solid with lustrous metallic luster. It is soft with a greasy feeling and excellent electrical conductivity. The graphite atoms form a planar layer 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. 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 and soluble with benzene. It is also 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.
