WebUnpurified graphites have typical impurity levels over 1000 ppm, of which, the major constituents are metals. Our purification process reduces impurities to 5 ppm (99.9995%) or less as determined by ash analysis. By removing metallic impurities, the oxidation threshold for our materials is increased by up to 50°C. Densification (BG) WebThe graphite material was found in the ultrasonic-assisted pulp (UP) ash, as shown by X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and TEM analysis. UP ash contained both inorganic and organic components.
