The internal structure of diamondThe internal structure of diamond consists of an infinite number of repeat units of identical cubical cells called the primary structural dimensions equal and set at 0.356 nm. These units lined up tightly in the three directions, without breaks between different crystal Vtkon Qdha and shape depending on the numbers and units and stage of growth where they stopped. Take the initial structural cell for diamond crystal cube-shaped (Figure 4 b) divided the elements of carbon Vttoda molecules in the centers of its faces, in addition to the four elements are placed in the centers of four of the eight Mkaabath the rotation. As such, each element carbon in the cell is linked to the nearest four elements carbon adjacent distributed symmetrically on the heads of four faces of a regular any with four faces triangular equal and are bound carbon to each other in all directions specific links Tkavih solid (Links atom) makes the distance between them is equal to 0.154 nm . And thus can be considered to develop the diamond model as one part of a huge atomic links with very strong earnings hardness, and diamond crystals is assumed in the model to be free of impurities and defects in their inner structure and this is what gives Hfofa highly visible to the light rays. However, the crystals proved to be whatever the net, and even decorative ones, including low rates of different impurities and defects in some cases up to 1810 in each element of 1 cm 3. Among the most important elements that marred: silicon, aluminum, calcium and magnesium. They are distributed on the outskirts of the structure of crystals with greater intensity than in Oasitha not exceed the diamond is generally 5%. In addition to the above, the diamond, especially the species is good of it, contains in the folds of his intention to Mandhanat solid very small Kalawlevin and pyroxene and chrome Spenal, graphite, quartz, iron oxides, etc.; also contains Manbsat liquid (water, acid, coal) and gas (nitrogen, etc.).
