摘要:
The invention relates to zinc powder or zinc alloy powder having an inhomogeneous bulk density depending on the particle size, whereby the difference in bulk density measured according to ASTM B212 at a size fraction smaller 75 νm vis-à-vis a size fraction greater 150 νm is at least 0.5 g/cm3 and the mean bulk density of the powder measured according to ASTM B212 ranges from 1.8 to 4.0 g/cm3. The invention also relates to mixtures of said zinc powders or zinc alloy powders and to an alkaline battery containing said powders.
