3)Product advantages
A)Chemical stability. Good chemical stability at room temperature, acid resistance, alkali resistance and organic solvent corrosion resistance.
B)High temperature resistance. The melting point of natural amorphous graphite is 3850±50℃, the boiling point is 4250℃. In the metallurgical industry, the product is mainly used to make graphite crucible, in steelmaking commonly used graphite as a protective agent of ingot, metallurgical furnace lining.
C)Good thermal and electrical conductivity. The electrical conductivity is hundreds of times higher than that of general non-metallic ores, and the thermal conductivity exceeds that of steel, iron, lead and other metal materials. The thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite becomes an insulator.
D)Thermal shock resistance. When used at room temperature, it can withstand the drastic change of temperature without damage. When the temperature changes suddenly, the volume of graphite changes little and will not produce cracks.
E)Good lubricity. The lubricating performance of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricating performance.
F)Plasticity. Graphite has good toughness and can be made into very thin sheets.
4)Applications
Natural amorphous graphite has a wide range of applications, mainly used in the production of high temperature crucible smelting, mechanical industry lubricants, the production of electrodes and pencil lead. In addition, it is also widely used in casting coatings, oil drilling, battery carbon rods, steel, casting materials, refractory materials, dyes, fuels, electrode pastes, and used as pencils, welding rods, batteries, graphite emulsion, desulfurizer, preservative anti-slip agent, smelting carburizer, ingot protection slag, graphite bearings and other products.
5)Remark
Keep dry when storing to avoid moisture.
