NIOBIUM – Ngwa maka ihe ọhụrụ nwere nnukwu ikike n'ọdịnihu
Niobium bụ ọla na-acha ntụ ntụ na-acha ọcha na-egbukepụ egbukepụ n'elu ebe a na-egbu maramara.E ji ebe mgbaze dị elu nke 2,477°C na njupụta nke 8.58g/cm³ mara ya.Niobium nwere ike ịmepụta ngwa ngwa, ọbụlagodi na obere okpomọkụ.Niobium bụ ductile na-apụta na tantalum n'ime ihe okike.Dị ka tantalum, niobium na-egosipụtakwa kemịkalụ pụtara ìhè na nguzogide oxidation.
