Application of niobium silicide in material

Niobium (Nb) is a kind of refractory metal with high melting point (2468℃), moderate density, corrosion resistance, radiation resistance, and high temperature strength, with good mechanical properties at high temperature. The excellent properties of niobium and niobium alloy make it one of the important candidate materials for high-temperature structural parts in aviation, aerospace and nuclear industry, which can be used to manufacture rocket engines, nuclear reactors and other key components. However, its poor oxidation performance, pure niobium at 600℃ [...]
