Graphite powder can also be classified according to purpose, nature, it can be said industry classification according to the application, can be divided into chemical use graphite powder, conductive graphite, lubricating graphite, graphite battery, sealed with graphite, graphite powder metallurgy and other graphite products. Due to its special structure Lacey graphite graphite manufacturers, and has the following special properties: 1) High temperature resistance: graphite melting point of 3850 ± 50 ℃, boiling point 4250 ℃, even after ultra-high temperature arc burning, weight loss is very small, thermal expansion coefficient is small. Graphite strength with temperature increase and strengthen graphite specifications, at 2000 ℃, the graphite strength doubled. 2) electrical conductivity, thermal conductivity: the conductivity of graphite higher than the average non-metallic minerals a hundred times. Thermal conductivity than steel, iron, lead, metal materials. Thermal conductivity decreases with increasing temperature, even at very high temperatures, the graphite into a thermal insulator. Graphite graphite can be conductive because each carbon atom with other carbon atoms is formed only three covalent bonds, each carbon atom remain a free electron to transfer charge. 3) lubrication: lubrication performance graphite flake graphite depends on the size of the graphite milk, the larger scales, the smaller the coefficient of friction, lubrication, the better the performance. 4) Chemical stability: graphite at room temperature have a good chemical stability to acid, alkali and corrosion resistance to organic solvents. 5) plasticity: graphite, toughness, and can be crushed into very thin slices. 6) thermal shock resistance: graphite used at room temperature can withstand dramatic changes in temperature will not destroy lives, when sudden changes in temperature, little change in the volume of graphite, will not crack.
