A Novel Technique for Synthesis of Nanocrystalline Cupper in Iran

Iranian researchers at University of Tehran, synthesized nannocrystalline cupper particles by mechanochemical reduction of Cuprite and investigated the kinetics of the process for better understanding of the possible mechanisms.

"Cupper nanopowder is prepared by mechanochemical reduction with graphite in a high-energy ball mill. The results confirm the formation of Cupper nanopowder from Cu2O in a single step process," Said S. Sheibani.

The average size of the nanocrystaline Cupper was measured to be 27 nm after 30 hours of milling. The nanopowder would have applications in microelectronics industry; to increase thermal conductivity of fluids.

This research project was carried out under the guidance of Dr. A. Ataie and Dr. S. Heshmati-Manesh, both from School of Metallurgy and Materials Engineering in University of Tehran.

The results was published in the International Journal of Modern Physics B, Vol. 22, Nos. 18 & 19 (2008) 2962-2969.
