1 thought on “What is the structure of the diamond”

  1. In crystal, diamond structure, also known as diamond cubic Lattice Structure, has diamonds. Each atom in diamond structure forms a positive tetraonal body with four adjacent atoms, so the number of atomic in the single cell is 5. In addition to diamonds with diamond structure, in addition to diamonds, there are silicon, 锗, α-tin.
    The structure

    The prototype of diamond structure is diamond crystal, also known as diamond. In diamond crystals, each carbon atom is used to form a covalent bond with the other four carbon atoms with the SP3 hybrid track, forming a positive tetraonal body. Because the C-C key in diamond is very strong, diamonds have high hardness and high melting point; and because all price electrons are limited in the common price bond area, there is no free electron, so diamonds are not conductive [1].
    Tracka structure.
    is a crystal structure made of 1/4 units embedded by the diagonal of the cubic cells of the two facial cubic cubic cells. ), Cube Crystal, FD-3M (No. 227) space group. If the crystal cells of cubic cells are A, the base of the original cell structure of the diamond structure is
    each original cells contain two atoms, and the coordinates in the original cells are
    and
    Each crystal study of diamond structure (ie, crystal cells) contains 8 atoms, and the coordinates in the crystal cells are
    The prototypes of diamond structure are the crystal structure of diamond structure. In diamond crystals, the 4 -price electrons of each carbon atom are hybridized by SP3 to form 4 completely equivalent atomic orbit, forming a covalent bond with the four adjacent carbon atoms. The angles between these four covalent bonds are equal, about 109.28 degrees, and the accuracy value
    , so as to form a positive tetraon structure unit composed of 5 carbon atoms. The apex, 1 carbon atom is located in the center of the positive tetraon. Because the covalent bonding is difficult to deform, the C-C key can be large, so the hardness and melting point of diamonds are high, and the chemical stability is good. The electrons in the covalent key are bound to the chemical bond and cannot participate in conductivity, so diamond is an insulator and does not conduct electricity.
    The space stacking ratio (also known as position ratio, also known as
    ) compared with the facial cubic structure (
    ) and hexagonal strength (related to the long shaft and short shaft, approximately similar to that of the short shaft, approximately related to the short shaft and short shaft. The facial cubic structure is the same) low, which is lower than the cube structure (
    ). But the atomic density of diamond structure (that is, the number of atoms in the unit space) is large. This feature is particularly significant to diamond, because the C-C key in diamonds is very small.

    The structural analysis
    Themighting structure is very similar to the structure of the light -zinc ore structure (Structure). Types, such as Zn and S, and the atoms that make up the diamond structure are the same species. The stacking ratio of the Diplochem structure changes with the relative size of the two atoms.
    Themugdis and graphite are also composed of carbon atoms, which are homogenic alien. Due to the different combination of carbon atoms, the nature of the two substances is very different. The carbon atoms in the graphite form a co -price bond according to SP2 hybrids. A co -price key is combined into a honeycomb structure on a plane. The binding between the same layer of carbon atoms is stronger than diamonds, so the melting point of graphite is higher than diamond. However, the combination of layers is weak, and it is easy to slip, so the hardness is very low. Three of the four -price electrons in the graphite atom in graphite form a covalent bond, and the other price electrons form a large
    key in the crystal, which can conduct electricity along the graphite layer.
    The difference between diamond and other carbon -gaming different types is also caused by different carbon atomic binding
    If artificial diamond

    The diamonds we often say are a mineral composed of pure carbon and the hardest substance in nature. Since the 18th century confirmed that diamonds were composed of pure carbon, people have started research on artificial diamonds. Only in the 1950s through the progress of high -voltage research and high -pressure experimental technology, real success and rapid development have been achieved. Artificial diamonds are also widely used in various industries and craft industries.
