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 first century AD, diamond was recorded in literature. During the next 1,600-year period, however, no one knew the actual composition of a 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 a mixture of carbon and oxygen called carbon dioxide. 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 studied diamond crystals with X rays. The scientists found 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 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, a diamond is a mineral that’s formed by squeezing the carbon atoms.

Synthetic diamond

It is the hardest material in nature. As such, it has many industrial applications, such as fine materials for abrasives, 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 hardness and the “king” of gems. Diamond crystals are angled at 54deg.44’8″. 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 has an oily feel and is electrically conductive. 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. It is stiffer than steel, with a hardness that is higher than diamond.

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 carbon nanotubes, or Bucky Tubes. The 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 material. C60 is also used in many different fields, including semiconductors.
