The preparation of nanometer copper powders by using NaH_2PO_2 as reductant;

Preparation of silver-plated copper powder and its properties;

Research on copper powder conductive acrylate press-sensitive adhesive;

5It was studied that the formation,structure and properities of the solid solution sintered from Cu powder and Ni powder using the method similar to powder metallurgy.

It is also showed that,by the second warm compaction,the monophase Cu-Ni solid solution is easier,Cu powder and Ni powder sinter has higher density and hard.

A tentative technique of preparing nanon Cu powder with CuSO 4 and NaH 2PO 2 as main raw materials was proposed.

Preparation of ultrafine copper powder with hydrazine hydrate as reducing agent;

Because of special physical and chemical properties, ultrafine copper powders have been used in many kinds of fields, such as conduction materials, catalysts, lubricant addition, nanocrystalline copper materials, medicine and so on.

The activation pretreatment of copper concentrate has been done by high energy ball mill,and ultrafine copper powder with average size less than 10 μm has been prepared by directly using copper concentrate and ultrasonic slurry electrolysis.

Study on the structure of Cu-Zn powder under annealing conditions;

The microstructures of Cu-Zn powder under different annealing conditions were studied.

The metallographic structures of Cu-Zn powder under different conditions were studied by SEM,TEM and XRD in this paper.

Influences of surfactants on wettability and floating property of bronze powders;

The main factors influencing the gloss of bronze powder was studied to solve the problem of low gloss.
