Abstract: Sulfur-free and expanable graphite was prepared by reacting of natural flake graphite with concentrated nitric acid and acetic acid using potassium permanganate as oxidant at 30℃. The best conditions of the preparation were screened out. The method of Mass Spectrum was utilized to analyze the expandable graphite.
