• Spherical Graphite is made by mechanization processing mainly Flake Graphite into a spherical shape.  It is produced from plate-shaped Flake Graphite.  Compared to Flake Graphite, it has a higher bulk density, a smaller specific surface area, and a smaller amount of oil absorption.  In addition, since it is spherical, it is possible to obtain conductivity, and anisotropy in the heat dissipation direction.

Main Applications

• Anode materials for secondary battery
• Filler materials for rubber resin
• Resin filler
