Expandable Flake Graphite | Asbury Carbons

The primary reason for “bisulfate” intercalation is to impart the ability of the treated flake graphite to intumesce, exfoliate, or expand when heated. Exfoliation is a true .. When grinding, screening, or otherwise reducing the particle size of flake graphite, cleavage parallel to the basal plane (basal pinacoid) occurs. The result is.

Formation of Graphite Structure in Carbon Crystallites - Springer Link

INTRODUCTION. The structural changes produced in carbon materials by high-temperature heat treatment, grinding, or neu- tron irradiation are always accompanied by changes in crystallite size [1–6]. These processes are usually con- sidered separately. According to Veselovskii [1], graph- itization of carbon materials at.
