Abstract

"CéLULA COM CáTODO A LEITO DESCENDENTE PARA ELETRODEPOSIçãO DE METAIS". é descrita uma célula (100) para eletrodeposição de metal a partir de soluções de íons metálicos na qual o cátodo (1) é formado por um leito descendente de esferinhas em crescimento; as esferinhas, retiradas da parte inferior do leito, são transferidas para a parte superior do compartimento catódico por meio de um conduto vertical externo (3).
