At present, the main products of tantalum and niobium industry include tantalum powder (capacitor grade metallurgical grade), tantalum wire and its alloy processing material (plate, belt, tube, rod, wire), target, tantalum oxide (industry, light glass, high purity), lithium tantalate, niobium powder (capacitor grade, metallurgical grade) . Its gold ingot, niobium and its alloy adding material (plate, belt, tube, rod, wire), niobium oxide (electrical, industrial, optical glass, high purity), carbide, lithium niobate single crystal, and superconductor.

  tantalum wires are the key materials for tantalum capacitors.Around 60% of the world's tantalum is used for capacitors.Tantalum and niobium targets are used in semiconductor devices and liquid crystal display technologies. niobium is used in the manufacture of ceramic capacitors and niobium capacitors. NB wires are used to produce high strength low alloy steel, stainless steel, heat-resistant steel, gap steel, carbon steel, tool steel, rail steel, cast steel, and about 90% of the world's niobium is used in steel Industry.

   Superalloy is produced by adding tantalum or niobium to tungsten, molybdenum, nickel, cobalt, vanadium, iron base alloy or adding other metal elements ，with tantalum and niobium as the base. Superalloy is an important structural material for aerospace engine, land based air turbine engine, modern weapon, bad industrial environment facilities. Tools and drilling tools made of TaC and Nb carbide can withstand high temperatures of nearly 3000 C, and their hardness is comparable to that of diamond.

   Due to the good superconductivity of niobium and tantalum, the addition 、 in the materials of wire and cable can greatly reduce the loss of electrical energy and thus save electrical energy. Tantalum and niobium are high-quality acid-resistant and liquid metal corrosion-resistant materials, which can be used in the chemical industry for cooking, heating, cooling and various devices and utensils. In addition, their alloys are also used as atomic energy reactor cladding materials and high-energy physical superconducting devices. At the same time, tantalum is an ideal bioadaptive material and is widely used in medical surgery.
