PRODUCT SPECIFICATIONS AND DETAILS
Micronized Graphite Powder is a fine graphite material produced through grinding, classification, and controlled particle size refinement of selected natural flake graphite or other suitable graphite feedstocks. Compared with conventional graphite powder, it offers a finer particle size range, more controlled particle distribution, improved dispersion behavior, and better compatibility with industrial formulations that require stable fine-particle performance.
In practical applications, buyers usually do not select micronized graphite powder by product name alone. Particle size distribution, D50 value, carbon content, ash level, moisture, surface behavior, and formulation compatibility can all influence the final result. For this reason, micronized graphite powder is commonly used where smooth mixing, good surface coverage, low-friction behavior, conductivity, or fine additive performance is required.
QDZRT Graphite can supply Micronized Graphite Powder in different micron grades for coatings, paints, inks, dry lubricants, greases, friction materials, sealing compounds, conductive fillers, anti-static materials, thermoplastics, elastomers, powder metallurgy, and specialty composite systems. Grades can be selected according to particle size distribution, carbon level, purity requirement, application direction, packaging format, and customer-specific processing needs.

How to Select the Right Micronized Graphite Powder
The most important selection factors are particle size distribution, carbon content, ash level, moisture, surface behavior, and compatibility with the final formulation. For most fine powder applications, buyers should pay attention to D50 and D90 values rather than relying only on mesh descriptions. A similar mesh description may still represent different dispersion behavior depending on grinding and classification quality.
For coatings, inks, and polymer systems, dispersion behavior and surface coverage are often important. For lubricants and friction materials, particle size, lubricity, and consistency may matter more. For conductive or anti-static applications, carbon level, particle size, loading ratio, and formulation system should be evaluated together.
Inquiry Information Needed
- Target application, such as coating, lubricant, ink, polymer, friction material, or conductive compound
- Required D50 / D90 particle size or current grade being used
- Carbon content, ash level, moisture, or purity expectation
- Whether BET surface area, tap density, pH value, or sulfur content is required
- Sample quantity, trial quantity, bulk order quantity, and packaging preference
- Any special handling, dispersion, or formulation compatibility requirement

FAQ
What is the difference between micronized graphite powder and ordinary graphite powder?
Micronized graphite powder is processed to a finer and more controlled particle size range. Compared with ordinary graphite powder, it is usually selected when better dispersion, smoother surface coverage, and more consistent fine-particle behavior are required.
Should I choose micronized graphite powder by mesh size or D50 value?
For fine graphite powder, D50 and D90 values are usually more useful than mesh size alone. Mesh descriptions can be used as a rough commercial reference, but particle size distribution data provides a clearer basis for formulation and processing evaluation.
Can micronized graphite powder be used in coatings and inks?
Yes. Micronized graphite powder is commonly used in coatings, paints, inks, and specialty surface systems where fine dispersion, conductivity, lubricity, or surface coverage is required. The suitable grade depends on particle size, carbon content, and formulation compatibility.
Is micronized graphite powder suitable for conductive or anti-static compounds?
Micronized graphite powder can be used in conductive fillers, anti-static compounds, conductive coatings, and selected polymer systems. The final conductive effect depends on graphite grade, particle size, loading ratio, dispersion quality, and the base formulation.
Can the particle size be customized?
Yes. Particle size distribution can be adjusted according to application requirements. Buyers can provide target D50 or D90 values, current grade references, or performance requirements for grade matching.
What information should I provide before requesting a quotation?
It is helpful to provide the target application, required particle size distribution, carbon content, ash level, moisture requirement, trial quantity, bulk order quantity, and packaging preference. If the product will be used in a formulation, information about the base system can also help with grade selection.
