Conclusions

  1. 1.

    The carbonate and hydroxide methods of manufacture of fine-grained silver-cadmium oxide composites do not give identical results, since the precipitates obtained differ in chemical composition, and the end products have different physicomechanical properties; the material produced by carbonate precipitation is slightly superior to the hydroxide precipitation material. The difference in quality between the two materials is linked with the state of the ultrafine dispersion forming during the process. In the hydroxide process cadmium oxide inclusions form during the thermal decomposition of the hydroxide precipitate, adversely affecting the thermal stability of the strengthening of the resultant material.

     
  2. 2.

    In view of the superiority of the carbonate precipitation material, it should be possible to reduce the amount of silver required in the manufacture of SOK15M contacts by changing over to the carbonate process.
