ZINC POWDER OR ZINC ALLOY POWDER HAVING AN INHOMOGENEOUS BULK DENSITY FOR USE IN ALKALINE BATTERIES |
摘要 |
Zinc powder or zinc alloy powder has an inhomogeneous bulk density distribution depending on the particle size. The difference of the bulk density measured according to ASTM B212 at a grain size amount of less than 75 mum to the grain size amount of more than 150 mum is at least 0.5 g/cm3 and the average bulk density of the powder according to ASTM B212 is in the region of 1.8-4.0 g/cm3. An Independent claim is also included for mixtures of zinc powder or zinc alloy powder. |
