Abstract

"Pó DE ZINCO OU Pó DE LIGA DE ZINCO, MISTURAS DOS MESMOS, E, BATERIA ALCALINA". A presente invenção se refere a pó de zinco ou pó de liga de zinco tendo uma densidade aparente não homogênea que depende da distribuição do tamanho de grão, a diferença da densidade aparente medida de acordo com a ASTM B212, na faixa de tamanho de grão menor do que 75 <109>m e na qual a faixa de tamanho de grão maior do que 150<109>m sendo de pelo menos 0,5 g/cm¬ 3¬, e a densidade aparente média do pó, medida de acordo com ASTM B212 varia de 1,8 a 4,0 g/cm¬ 3¬. A invenção ainda se relaciona a misturas dos referidos pós de zinco ou pós de liga de zinco e a uma bateria alcalina contendo os referidos pós.
