中文摘要	Ultrafine copper powders were prepared by direct reduction method with hydrazine hydrate and formaldehyde as composite reductive agent and glucose prereduction method, respectively. XRD and SEM analysis revealed that pure copper powders with single crystal 1 mu m can be prepared using hydrazine hydrate and formaldehyde as composite reductive agent. It exhibits good dispersity and stability in air. The grain size of the copper single crystals could be further increased to 2 mu m by glucose prereduction method, and the uniformity and diversity have also been improved.
