Wholesale Natural Micronized Graphite

High purity micronized (or micronised) grades of natural crystalline graphite with particle sizes (d50 = Cumulative 50% diameter) between three and sixty microns, on average.

Graphite ore is concentrated by mechanical and chemical purification processes, until it reaches a carbon content up to 99.9%. It is then submitted to milling in a laboratory equipped with jet and hammer mills, as well as particle classifiers employing state of the art technologies. Customization is available.

Lot sizes available: Big bags up to 750 kg, and pallets in 1,000 kg (2,204.6 pounds, or 1 metric ton) and up, depending on the grade.

Minimum Order Quantity: 20 metric tons (20' Dry Cargo Container)
