There are two processes in industry: direct carbon reduction and indirect carbon reduction. The niobium produced by direct carbon reduction is spongy with large surface area and low content of metal impurities and nitrogen, which is beneficial to the specific capacity of niobium powder. Therefore, the process is suitable for the production of capacitor grade niobium powder. The characteristics of indirect reduction are large production capacity of equipment, stable process, dense metal niobium bar and regular dimension, which are suitable for making niobium bar, niobium ingot and niobium processing material.
