Introduction and application of niobium alloy

Since niobium was first purified, its properties have been paid close attention to by scientists and engineers, and it has been widely used in modern science and technology and industry. In fact, compared with other refractory metals, niobium has been used in different fields because of its high melting point (2468℃), low density, corrosion resistance, superconducting electrical properties and the ability to form dielectric oxides.

Of course, most applications depend on the purity of niobium, as does its potential usefulness, especially in superconducting applications. In order to obtain higher purity niobium, scientists and technicians have made a lot of efforts, obtained a lot of useful knowledge, and greatly improved the technical level of production ability.

The emergence of electron beam melting (EBM) technology has greatly promoted the production of niobium metal, which can produce a saw with lower residual impurities than the traditional solidification method.

Nb-10%Hf-1%Ti alloy is the first important high temperature Nb- based alloy developed. Niobium C-103 alloys have been used in high temperature components of turbine engines. Later, high purity niobium and some niobium alloys have been used in superconductivity. Nb-47%Ti alloys, which have been the greatest demand for niobium-containing alloys, are used in superconducting magnetic poles, which are used in magnetic resonance imaging (MRI) units. At present, high purity niobium powder has been widely used in solid electrolyte industry as a potential competitive object of niobium.
