Product core

Micronized Graphite Powder is produced from high-purity petroleum coke through advanced airflow pulverization and high-temperature graphitization (2800-3000℃), achieving ultra-high purity (carbon content ≥99.9%) and precise particle size control (1-60μm). Its core advantages lie in balanced excellent conductivity, low friction coefficient, and extreme heat resistance (>3000℃), making it a key material for high-performance applications in energy storage, metallurgy, and advanced manufacturing. The production process strictly controls impurities, with ash content ≤0.3% and sulfur content ≤0.02%, ensuring stable operation in harsh industrial environments.

Product features

Ultra high purity: Micronized graphite powder features fixed carbon content ≥99.9%, ash content ≤0.3%, and heavy metal impurities (lead < 3ppm,mercury < 0.1ppm) that meet RoHS standards, making it suitable for precision electronics and battery fields.
Precision particle size control: Narrow particle size distribution with adjustable median particle size (D50) ranging from 2 to 40 μm (customizable up to 1 μm grade). Laser diffraction testing ensures stability of D10/D50/D90 ratios, exemplified by lithium battery-grade products with D50=14±2 μm and D90=28±4 μm.
Excellent dispersion: airflow crushing technology improves the sphericity of particles, which can be evenly dispersed in coatings, pastes and composites without agglomeration.
Extreme heat resistance: can withstand 3000℃ high temperature in an inert environment, low thermal expansion coefficient, suitable for refractory materials.
Dual function characteristics: it has both high conductivity (resistivity ≤10μΩ・m) and self-lubrication performance (friction coefficient <0.15), which is suitable for both conductive and lubricating scenarios.
Chemical inertness: insoluble in water, acid and organic solvent, resistant to molten metal and slag corrosion, prolonging the service life of metallurgical process.

Product use

Lithium ion battery: as an anode material (D50=14-21μm) can achieve about 355mAh/g capacity and 1.65-1.75g/cm³ compact density; as a conductive additive (5-10μm), it can reduce the internal resistance of the electrode.
High temperature lubrication: ultrafine grade (3-7μm) is used as dry lubricant, suitable for mechanical lubrication under-75℃ to 700℃ working conditions, suitable for automotive bearings and industrial gearboxes.
Refractory materials: 30-60μm particles can improve the thermal shock resistance of graphite crucible and furnace lining, used in steelmaking and ferroalloy smelting.
Conductive coating: 10-30μm powder can form a continuous conductive film, used for electronic device anticorrosion coating and electrostatic shielding.
Environmental protection engineering: 10-20μm powder because of its large specific surface area (3-10m²/g), it is used for oil adsorption and pollutant removal in wastewater treatment.
Electronic slurry: 2-5μm ultra-fine grade is used for silver-graphite composite slurry, suitable for chip packaging, to ensure stable transmission of current.
