Aphanitic graphite Aphanitic Aphanitic graphite graphite, also known as microcrystalline graphite or earthy graphite carbon graphite, graphite crystal diameter which is generally less than 1 micron, the specific surface area in the range of focus 1-5m2 / g, microcrystalline Qingdao graphite graphite aggregates only under an electron microscope to see the crystal form. Such graphite surface is characterized by earthy, lack luster, lubricity somewhat less than the flake graphite. Higher grade. Usually 60 to 85%. Few as high as 90%. More generally used in the foundry industry. The main hidden in Chenzhou, Hunan Lu Tong. With the increase of this graphite purification technology. Amorphous graphite is widely applied. Since the carbon atoms arranged in close thermal lattice vibration difficulties in crystallization of graphite atomic layer of graphite to high temperature and thus a special thermal properties. Graphite melting point of 3850 ℃, boiling point of 4250 ℃, heat absorption 6.9036 × 107J / kg, the high temperature arc ignition weight loss extremely small colloidal graphite, at 2500 ℃ its strength increased by 1 than the normal temperature, the thermal expansion coefficient ( 1.2 × 10-6), sudden changes in volume when the temperature changed little. Since electrons flow easily in the presence of graphite crystal, and therefore its conductivity, thermal conductivity less than the metal.
