The CdO powders synthesis by a thermal decomposition of unstable salts for arcing electro contact materials

The synthesis process of CdO powders was studied by thermal decomposition of nitrate and acetic cadmium. TGA, DSC, XRD and SEM were used for a investigation of these powders. Powders are intended for composite materials of switching electrocontacts with a fine-grained and homogeneous microstructure. The CdO powders were obtained under identical conditions have essentially differed on morphology and dispersion. This difference is defined be used salt. The cadmium acetate is more preferably for synthesis composite mixture for an electrocontacts material.
