High Purity Graphite Material
High purity graphite is a kind of high-quality graphite carbon material. When it is made, an organic compound with strong acid resistance is added. After a series of processes such as high-pressure forming and high-temperature heat treatment, it can effectively reduce the porosity of graphite products, improve the volume and density of the products, and has good acid resistance and wear resistance. Because of its good physical and chemical properties, high purity graphite is also gradually used as the main material for mold making.
Advantages of high purity flake graphiteMaterial
01
High-temperature resistance: the melting point of graphite is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even if it is burned by an ultra-high temperature arc, the weight loss is very small, and the coefficient of thermal expansion is also very small. The strength of graphite increases with the increase of temperature. At 2000 ℃, the strength of graphite is doubled.
02
Conductivity and thermal conductivity: the conductivity of graphite is 100 times higher than that of non-metal. The graphite thermal conductivity exceeds that of steel, iron, lead, and other metal materials. The coefficient decreases with the increase of temperature. Even at very high temperatures, graphite becomes an insulator. High purity graphite can conduct electricity because each carbon atom in graphite only forms three covalent bonds with other carbon atoms, and each carbon atom still retains one free electron to transfer charge.
03
Lubricity: the lubricity of graphite depends on the size of the graphite scale. The larger the scale is, the smaller the friction coefficient is, and the better the lubricity is.
04
Chemical stability: high purity graphite has good chemical stability at room temperature, and is resistant to acid, alkali, and organic solvent corrosion.
05
Plasticity: high purity molded graphitehas good toughness and can be rolled into thin sheets.
06
Thermal shock resistance: when graphite is used at room temperature, it can withstand the drastic change of temperature without damage. When the temperature changes suddenly, the volume of high purity graphite changes little, and there will be no cracks.
