NIOBIUM - ihe eji emepụta ihe ọhụrụ nwere nnukwu ike n'ọdịnihu
Niobium bụ ígwè isi awọ dị mfe nke nwere ọdịdị ọcha na-egbukepụ egbukepụ n'elu elu e ji aka mee. A na-amata ya site na ebe agbaze dị elu nke 2,477°C na njupụta nke 8.58g/cm³. A pụrụ ịmepụta Niobium ngwa ngwa, ọbụlagodi na okpomọkụ dị ala. Niobium na-agbanwe agbanwe ma na-apụta na tantalum n'ime ihe e kere eke. Dị ka tantalum, niobium nwekwara iguzogide kemịkalụ na oxidation pụrụ iche.
