How to Select Graphite Powder by Purity, Mesh and Application

Many buyers face poor dispersion, insufficient lubrication or conductivity failure because they select the wrong graphite powder grade. Three core parameters need confirmation before ordering: fixed carbon content, particle size (mesh), and graphite type (natural flake or synthetic).

Many buyers face poor dispersion, insufficient lubrication or conductivity failure because they select the wrong graphite powder grade. Three core parameters need confirmation before ordering: fixed carbon content, particle size (mesh), and graphite type (natural flake or synthetic).

Graphite Powder

Natural flake graphite powder has better lubricity, suitable for release agent, dry lubricant and refractory coating. Synthetic graphite powder has higher consistency, better conductivity and rounder particle shape, preferred for battery conductive additives and high-end conductive composites. Coarse mesh powder is low-cost for casting coating; ultra-fine micron powder is for high-end conductive slurry and thin-layer coating.

If used in air at high temperature, graphite powder will gradually oxidize above 600℃. Anti-oxidation additives can be compounded as required. Jiecheng Graphite offers sample testing service to verify lubrication, conductivity and dispersion performance before mass order. We match the most cost-effective grade according to your formula and process.
