Abstract

MÉTODO PARA A PRODUÇçO DE Pà DE NÍQUEL METÁLICO FINO, DE BAIXA DENSIDADE VOLUMÉTRICA. Método de produção de um pó de níquel fino, de baixa densidade volumétrica compreendendo: a) o carregamento de partículas de pelo menos um sal de níquel redutível dentro de um forno de modo a formar um leito em movimento de carga do forno; e b) a redução da carga do forno com um gás contendo H2 em uma temperatura oscilando de cerca de 3000C a cerca de 5000C, o leito de carga do torno sendo movido suavemente de modo a minimizar a formação de aglomerados duros e obtendo um pó de níquel fino, de baixa densidade volumétrica. Método similar, em que a carga do forno é estática e está contida dentro de um leito superficial.
