Graphitized carbon blacks

WebA graphitized carbon black (GCB) can be non-porous or porous. The graphitization process results in a highly pure surface with great adsorption and desorption (if required) properties. Surface interactions depend solely on dispersion (London) forces. These particles are: Granular. Friable.
