產品描述

Dia 2.0 Niobium Wire 


Niobium has an abundance of 20 parts per million in the earth's crust, ranking 33rd among all elements. Some
scientists believe that niobium is higher in the entire earth, but
mainly concentrates in the core because of its high density. Niobium does not appear in nature as a pure state, but rather combines with other elements to form minerals. These
minerals generally also contain tantalum elements, such as ferrite (ie,
Fe (Fe, Mn) (Nb, Ta) 2O6) and columbite (Fe, Mn) (Ta, Nb) 2O6. Minerals containing niobium and tantalum are often secondary minerals in pegmatites and alkaline intrusive rocks. Other
minerals include calcium, uranium and thorium as well as rare earth
niobates such as pyrochlore (Na, Ca) 2Nb2O6 (OH, F) and black lean gold
(Y, Ca, Ce, U, Th ) (Nb, Ta, Ti) 2O6) and the like. These
large-scale niobium deposits occur near carbonate rocks, a type of
carbonate and silicate igneous rock, and are also a component of
pyrochlore.
