Ultrasonic Grinding of Natural Graphite - NASA/ADS

FINE grinding of graphite is usually carried out in a mortar or in a ball mill. The reduction of the particle size proceeds rather slowly due to the lubricating action of the grain surfaces, and the ground crystals contain various kinds of lattice imperfections including stacking faults-the extent of the imperfections being subject to the period and method of grinding. Recently, Bacon1 ...
