• ultrasound cavitation
• microcrystalline diamond

Diamond microcrystals have been synthesized using ultrasonic cavitation of a suspension of hexagonal graphite in various organic liquid inedia, at an average bulk temperature of the liquid up to 120 degrees C and at atmospheric pressure. The yield of diamond is up to 10% by mass. The diamonds were characterized by scanning electron microscopy, X-ray diffraction and laser Raman spectroscopy, Analysis of the crystallite size distribution showed that the diamonds were nearly mono-dispersed, having a size 6 or 9 mu m +/- 0.5 mu m, with cubic, crystalline morphology.
