According to the ideal graphite sample Bernard provided, graphite structure is a plurality of parallel to the base surface level of oil continuous composite made. Each layer of carbon atoms arranged in a hexagonal graphite Lacey sold three adjacent carbon atoms covalently bonded graphite roughness quality, becoming a second degree mesh flat stretch of infinite space, called the basal plane. Stacked sequentially phase shifted base surface, as shown in FIG. Unit cell a = 2.4612 ± 0.00001 ?, e = 6.7079 on 0.0007 ?. Interlayer distance: 3.3538 ?, capacity: 35.190 ?. Atoms, 4. Second Density: 2.266 g / cm, the same position every layer of carbon atoms, becomes AB, AB, AB. . . The three-dimensional ordered, was dense hexagonal stacking. Therefore, graphite on crystallography classification is hexagonal. Each layer between the metal bond strength between the level of activity by the electron cloud provided linked interlayer distance 3.35.8 Egypt, the binding energy of 4.36 kcal / g-atom, it changes very little with temperature graphite, by 4 kcal of a 196 degrees / gram atom to 3.6 kcal of 1118 degrees / gram atom, and the atom on the same plane spacing 1.415 ?, their binding ability to 170 kcal / gram atom. Each unit cell has four carbon atoms. Root causes of graphite carbon equivalent is floating too high. Thick slow solidification time provide conditions for floating graphite, graphite floating exacerbated. RE eutectic point to the left, above the residual amount of rare earth O. When 06% of graphite, graphite floating increased significantly. Magnesium eutectic point right, raise the amount of residual magnesium, reducing graphite float. Prolonged high temperature molten iron pouring remain liquid in the type of time, increasing the graphite float. Burden original graphite large size, quantity, unmelted graphite particles promote the nucleation of graphite and graphite under floating liquid precipitation. Because graphite has many excellent properties, and thus in the metallurgical, mechanical, electrical, chemical, textile, defense and other industries widely used. Can be used for refractories. Graphite flake graphite products to maintain the original chemical properties also has a strong self-lubricating properties. Characteristics of the graphite powder, i.e. the acid resistance of high strength, corrosion resistance and high temperature and low temperature 3000 ℃ -204 ℃, while its compressive strength is greater than 800kg / Cm2, and antioxidant, a 1% weight loss at 450 ℃ air, the spring rate 15-50% (density of 1.1-1.5). So graphite products has been widely used in metallurgical, chemical, petrochemical, high-energy physics, aerospace, electronics and other areas.
