Mesophase Graphite Powder

 

Made in Taiwan by China Steel Chemical Corporation

Distributed in North America by Pred Materials

Product Description

A commercial coal tar pitch was thermally treated to form anisotropic mesophase spherules. The resulting mixtures were then washed, filtrated and dried. Series of Green Mesophase Powders were obtained. The particle size can be modified by controlling reaction parameters. The received green mesophase spherules were then carbonized and graphitized to yield anode mesographite materials: Mesophase Graphite Powder (MGP), Fine Mesophase Graphite Powder (FMGP) and Super Fine Mesophase Graphite Powder (SMGP).

We control particle size from precursor (xGMP) level!

=> No crush, no grinding process.

=> Stable particle size & all spherical micro-bead.

=> Less product variation in shape & properties.
