Tantalum is used to make tantalum capacitors: tantalum powder and tantalum wire are the key materials to make tantalum capacitors, which are the best capacitors. Niobium can also be made into capacitors. Tantalum is used for making high tantalum products: tantalum has high capacity, good strength and stiffness, and is a high quality material for making heating parts, heat insulation parts and charging vessels for vacuum blast furnaces. Tantalum and niobium are used to make corrosion-resistant tantalum and niobium products: tantalum and niobium are high quality corrosion-resistant materials of acid and alkali and liquid metal, which can be used to make digesters, heaters, coolers, various utensils and devices in chemical industry. Application of tantalum and niobium in aerospace industry: used for making engine parts of aerospace aircraft, rockets and submarines, such as combustor, combustion duct, turbine pump, etc. Such as WC-103 Nb-Hf-Ti high niobium base alloy is high quality aerospace materials, used as rocket accelerator nozzle, spacecraft propulsion afterburner and nozzle valve. Tantalum carbide as additives 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 the main additive for steel: the addition of niobium microalloy steel, the grain refinement of steel, can improve the strength and toughness of steel, about 75% of niobium is used in this field. Niobium used as superconducting material: Nb-Ti alloy is the most widely used superconducting material with the largest amount. It 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. Nb3Sn is second only to Nb-Ti in practical superconducting materials. Tantalum oxide and niobium oxide are the raw materials for tantalum and niobium artificial crystals. Ta2O5 and Nb2O5 are the raw materials for crystals such as LT and LN. LT and LN are important piezoelectric, thermoelectric and nonlinear optical materials, which have important applications in laser and micro-acoustic surface wave technology. Cathode sputtering tantalum coating, tantalum active materials for high vacuum suction pump, Nb2O5 and Ta2O5 as optical glass modifiers and chemical catalysts, Ta, Nb applications in medical devices and arts and crafts, etc.
