Artificial graphite powder
Artificial graphite powder is a synthetic carbon material developed for industrial applications that demand controlled purity, stable performance, and reliable supply. Unlike natural graphite, it is manufactured through a high-temperature graphitization process, allowing tighter control over composition and consistency. This makes it a dependable option for customers who prioritize repeatability and predictable behavior in production.
Product Description
Artificial graphite powder is produced from petroleum coke or needle coke through calcination, milling, and graphitization at temperatures above 2,500°C. This process removes most volatile impurities and results in a carbon material with a highly ordered graphite crystal structure.
Because it is synthetically produced, artificial graphite powder avoids the variability often associated with natural ore sources. In practice, this means more consistent carbon content, ash level, and particle characteristics from batch to batch—an important factor for industrial users placing repeat orders.

Key Product Advantages
High Purity and Consistency
Artificial graphite powder offers low impurity levels and minimal variation between production batches. This consistency is particularly valuable in applications where formulation stability or electrical performance must be maintained over long production cycles.
Controlled Particle Characteristics
Through precise milling and classification, particle size and distribution can be tailored. This improves dispersion behavior in polymers, coatings, and metal matrices, reducing processing issues such as segregation or uneven conductivity.
Excellent Thermal Stability
The material maintains chemical and structural stability at high temperatures in inert or reducing atmospheres. This makes it suitable for metallurgical processing, refractory additives, and high-temperature functional components.
Reliable Electrical Performance
Artificial graphite powder provides predictable electrical conductivity, supporting its use in conductive materials, electrodes, and energy-related systems where performance variation is not acceptable.
Typical Application Areas
Battery and Energy Materials
Used as a conductive additive or base material in battery components where purity and consistency are critical.
Powder Metallurgy
Acts as a carbon additive or processing aid, enabling controlled carbon content and uniform mixing.
Conductive Polymers and Coatings
Incorporated into plastics, rubbers, and coatings to impart stable electrical conductivity and antistatic properties.
Refractories and High-Temperature Materials
Used to enhance thermal resistance, oxidation resistance, and structural stability in refractory formulations.
Industrial Lubrication (Specific Grades)
Certain artificial graphite powders are applied in dry lubrication systems where controlled purity is required.
