From Roskill's website:
Demand for niobium is driven by two sets of factors. One is the overall growth in the global economy, which directly influences the demand for steel, where most niobium is used, and the demand for aerospace superalloys, which are the largest non-steel market. Future demand for niobium will follow the overall economic trend, at the very least. The other factor is the incidence of use in steel, which could be the principal driver of structural increases in demand in the coming years
