Conclusions

  1. 1.

    In the autoclave deposition of copper, it is possible to employ various polyacrylamide derivatives and acrylic acid as well as AMF grade polyacrylamide.

     
  2. 2.

    The particle size and shape of the powder produced can be controlled by varying the type of SAS.

     
  3. 3.

    Use of various SAS and of repeated consolidation cycles enables the physicotechnological properties of copper powders to be varied between wide limits. Thus, a two-cycle deposition process can yield powders with apparent densities of 0.96–1.82 g/cm3, specific surfaces of 425–1800 cm2/g, and flowabilities of up to 2.27 g/sec; by varying the number of consolidation cycles, it is possible to produce powders with apparent densities of 0.49–2.49 g/cm3, specific surfaces of 340–2260 cm2/g, and flowabilities of up to 4.17 g/sec.

     
  4. 4.

    The properties of deposited powder can be altered slightly and its carbon and sulfur contents reduced substantially by subjecting it to an annealing operation.
