title: Complex particles produced from graphite powder by acoustic cavitation in water.
abstract: Spaghetti-like structures made of fibers whose diameter are of about 1-2 microns, straight structures from about 10-20 microns and optically semitransparent particles, with linear dimension up to about 0.3 mm, were obtained from fine graphite powder in water subjected for 20 h to acoustic cavitation at a frequency of 19.5 kHz. A picture of spaghetti-like structures obtained by scanning electron microscopy is reported. From X-ray diffraction pattern, it was found that the semitransparent precipitates have an amorphous nature.
