Abstract

Patente de Invenção: <B>"Pó DE METAL REFRATáRIO DE BAIXO OXIGêNIO PARA METALURGIA DO Pó"<D>. A presente invenção refere-se a processos para a produção de produtos de metalurgia de pós de Ta/Nb formados usando-se pós de hidreto de Ta e/ou Nb com um teor de oxigênio maior que de um nível alvo, por exemplo, 300ppm, aquecendo-se o hidreto de metal na presença de um outro metal tendo uma afinidade maior pelo oxigênio, removendo-se o outro metal e quaisquer subprodutos da reação para se formar um pó de metal com um teor de oxigênio menor que do nível alvo e formando-se um produto metalúrgico a partie do pó de Ta/Nb reduzido por oxigênio mencionado com um teor de oxigênio menor que o nível alvo.
