Abstract

"TERMINAIS DE GRAU DE CAPACITOR COM RESISTêNCIA à TRAçãO E DUREZA AUMENTADAS". A presente invenção refere-se a um terminal de grau de capacitor feito a partir de metalurgia de pó, contendo pelo menos nióbio e silício, em que o nióbio é o metal com a maior percentagem em peso presente no fio de nióbio. O fio tendo uma resistência à tração controlada em um diâmetro final que excede a resistência do fio de grau de capacitor formado por metalurgia de lingote. Além disso, a dureza do fio de metalurgia de pó excede a do fio de grau de capacitor formado a partir de metalurgia de lingote com perda elétrica atendendo as especificações normalmente aplicadas a terminais de grau de capacitor de tântalo, nióbio ou nióbio-zircónio em temperaturas de sinterização de cerca de 1150<198>C e acima.
