Grafene grado H

Graphene are unique nanoparticles consisting of short stacks of graphene sheets having
 platelet shape. Each grade contains particles witha similar average thickness and surface area.
 

Grade M particles have an average thickness of approx 15 nanometers and a typical surface
area of 50 / 80 m2/g. Grade H is available with average particle diameters of 5, 15 or 25 microns.
