Tantalum is used to make high temperature resistant tantalum products

With high temperature resistance, good strength and stiffness, tantalum is a high quality material for heating parts, heat insulation parts and filling vessels used in vacuum furnace

3

Tantalum and niobium are used to make corrosion-resistant tantalum and niobium products

Tantalum niobium is a high quality corrosion-resistant material of acid and alkali and liquid metal, which can be used to make digesters, heaters, coolers and other utensils in chemical industry

Tantalum is used in the lining of armour-piercing shells

This application is currently mainly in the United States, is a missile, such as the TOW2B missile

6

Tantalum carbide as an additive for cemented carbide

Cemented carbide is mainly used as tools, tools, molds and wear-resistant structural parts, adding TaC can improve its hardness, strength, melting point and other properties. NbC can also be used, inferior to TaC

Niobium is a major additive in steel

The addition of niobium microalloyed steel can refine the grain size of steel and improve the strength and toughness of steel. About 75% of niobium is used in this field

8

Niobium is used as a superconducting material

Nb-ti alloy is the most widely used superconducting material with the largest amount, such as Nb 47 Ti, which has important applications in high-energy physics and is the preferred practical superconducting material for high-energy particle accelerators such as the Large Hadron Collider and heavy ion Collider. Nb 3 Sn is second only to NB-Ti in practical superconducting materials.

Tantalum oxide and niobium oxide are the raw materials of tantalum niobium artificial crystal

Ta 205 and Nb 205 are the raw materials for the fabrication of LT and LN crystals. LT and LN are important piezoelectric, thermoelectric and nonlinear optical materials, which have important applications in laser and micro-acoustic surface wave technology

10

Application of niobium in atomic energy industry

Nb has small neutron capture cross section, high thermal conductivity and high strength, and is used as nuclear fuel cladding material, nuclear fuel alloy additive, and heat exchanger structural material in atomic reactors
