PRODUCT SPECIFICATIONS AND DETAILS
Natural Graphite Powder is a carbon-based industrial raw material processed from natural graphite ore, including natural flake graphite and amorphous graphite. Depending on carbon content, ash level, particle size, powder morphology, and purification level, it can be used in applications requiring lubricity, thermal resistance, electrical conductivity, chemical stability, and cost-effective carbon performance.
Compared with synthetic graphite powder or highly purified specialty grades, Natural Graphite Powder is often selected when customers need a practical balance between performance, availability, and cost. It is widely used in refractory materials, friction products, coatings, sealing materials, conductive fillers, metallurgical additives, foundry materials, lubricating formulations, and general industrial carbon systems.
QDZRT Graphite can supply Natural Graphite Powder in different carbon grades, particle size ranges, and powder structures. Available options may include flake-type graphite powder, amorphous graphite powder, fine powder grades, and application-oriented specifications for downstream manufacturing and bulk industrial supply.

How to Select the Right Natural Graphite Powder
Selection should be based on the actual application rather than product name alone. For refractory and metallurgical use, carbon content, ash level, thermal behavior, and particle size are often important. For friction materials and lubricating systems, lubricity, particle shape, and formulation compatibility may matter more. For conductive fillers, carbon content, particle size, dispersion behavior, and loading ratio should be evaluated together.
Natural flake graphite powder is generally preferred where flake morphology, conductivity, lubricity, or higher carbon content is required. Amorphous graphite powder may be selected for more cost-sensitive industrial applications where a practical carbon source is needed. Fine powder grades can be selected when smoother mixing, better dispersion, or more uniform surface coverage is required.
Inquiry Information Needed
- Target application, such as refractory, friction material, conductive filler, sealing compound, metallurgy, or lubricant
- Required carbon content or fixed carbon range
- Expected particle size, mesh size, or D50 reference if available
- Ash content, moisture, volatile matter, or pH requirement
- Preferred graphite type: flake graphite, amorphous graphite, or fine powder grade
- Sample quantity, bulk order quantity, packaging preference, and delivery requirement
Packaging and Supply
Natural Graphite Powder is usually packed in moisture-proof paper-plastic bags, kraft bags, or jumbo bags according to order quantity, particle size, and export requirements. Custom packaging, particle size adjustment, carbon grade matching, and application-oriented supply options are available for bulk industrial customers.
The product should be stored in a sealed, dry, and well-ventilated environment, protected from moisture, contamination, and unnecessary exposure during transportation and storage. Proper packaging and storage help maintain powder consistency and downstream processing stability.

If you need material for friction products, refractory compounds, conductive systems, sealing materials, metallurgical additives, or general industrial carbon formulations, we can recommend a suitable grade according to your technical requirements.
FAQ
What is the difference between natural flake graphite powder and amorphous graphite powder?
Natural flake graphite powder is processed from flake graphite and usually has a more obvious flake structure, better lubricity, and stronger conductivity potential. Amorphous graphite powder is often selected for cost-effective industrial carbon applications where strict flake morphology is not required.
How should I choose the carbon content of Natural Graphite Powder?
The suitable carbon content depends on the application. Refractory, conductive, and higher-performance formulations may require higher carbon content, while some bulk metallurgical or foundry applications may use more cost-effective industrial grades.
Is mesh size enough for selecting graphite powder?
Mesh size can be used as a commercial reference, but particle size distribution or D50 data is often more useful for fine powder applications. For coatings, conductive fillers, sealing compounds, and lubricating systems, dispersion behavior and particle distribution should also be considered.
Can Natural Graphite Powder be used as a conductive filler?
Selected natural graphite powder grades can be used in conductive coatings, plastics, rubber compounds, and anti-static materials. Conductive performance depends on graphite grade, carbon content, particle size, loading ratio, and formulation design.
Can the particle size and carbon content be customized?
Yes. Particle size, carbon content, ash level, packaging format, and application-oriented grade selection can be discussed according to customer requirements and downstream processing conditions.
What information should I provide before requesting a quotation?
Please provide the target application, required carbon content, particle size or D50 value, ash requirement, preferred graphite type, trial quantity, bulk order quantity, and packaging preference. This information helps select a more suitable Natural Graphite Powder grade.
