Preparation of Nanometer Copper Powder Used Glucose Pre-reduction and Hydration Hydrazine Liquid Phase Method

Through the single-factor conditions test,the condition in which the glucose pre-reduction and hydration hydrazine liquid phase method was found. Then through the orthogonal method the best reducted condition was obtained. Verification tests show that the high purity metal powder products can be manufactured by the method,and structural components can be better controled,the materials is low-cost,the products particle size distribution is narrow,and the particle size is small. The reduction reaction is completed thoroughly,and CuO,Cu2O and other impurities are not easy to produce.
