Niobium is a very important superconducting material to produce high-capacity capacitor.
Niobium powder is also used to produce tantalum.
The pure Niobium metal powder or Niobium Nickel alloy is used to make Nickel, Chrome and Iron base high temperature alloy. Such alloy is applied to jet engines, gas turbine engines, rocket assembly, the turbocharger and the heat of combustion equipment;
By adding 0.001% to 0.1% Niobium nano powder is good enough to change the mechanical properties of steel
Due the coefficient of thermal expansion of Niobium is very similar to the sintered alumina ceramic material of the arc lamp, Nb nano powder could used as sealed material of the arc tube.
At present, the production of metal niobium products can be divided into two main categories: first, niobium; The second is niobium powder. In terms of smelting process, there are two basic methods, namely, metal thermal reduction method and molten salt electrolysis method.
Niobium is a major component of heat resistant alloys, high strength low alloy steels, high temperature alloys and stainless steels.
High purity niobium has good ductility and thermal conductivity and is mainly used in the manufacture of high-end technology products.
At present, niobium powder is mainly prepared by reducing high-purity compounds of niobium (oxides, fluoride salts, chloride) at high temperature. The process is long, the energy consumption is high, and the environment is polluted, which makes the cost of niobium high, the supply is less, and its application field is limited. Therefore, the development of a short process, low cost, environmentally friendly niobium production process has become a hot topic in recent years, among which molten salt electrodeoxidation (FFC) is widely concerned.
