Rare metal material technology is one of the most important subjects in the field of materials science and engineering in the new century. Modern high-tech such as information technology, new energy technology, space technology, biotechnology, superconductivity technology and other developments are closely related to rare metal materials, especially tantalum niobium new materials.
Tantalum niobium new materials have more and more development space in high-tech field. Secondly, the cutting tool of hard alloy is developing towards the direction of super hard and micro fine tip. Tantalum-niobium application in aerospace industry tantalum-niobium base alloy and other special alloys will continue to develop steadily. In recent years, special niobium steel demand continues to grow, in addition to developed countries, third world countries also have demand. Special superconducting materials will be used in a large number of magnet materials and high-tech computing technology, and is being further developed, tantalum niobium materials will continue to be developed in new applications. According to the development of the world's high-tech industry, tantalum niobium industry will maintain a growth rate of more than 12% in the next 5-10 years.
At present, tantalum niobium industry's main products include tantalum powder (capacitor grade metallurgical grade), tantalum wire, tantalum carbide, tantalum and its alloy ingots, tantalum and its alloy processing materials (tantalum plate, tantalum belt, tantalum tube, tantalum rod, tantalum wire), tantalum target, tantalum oxide (industrial, optical glass, high purity), lithium tantalate single crystal; Niobium powder (capacitor grade, metallurgical grade) niobium bar, niobium and its alloy ingots, niobium and its alloy additive materials (niobium plate, niobium strip, niobium tube, niobium rod, niobium wire), niobium oxide (electrical grade, industrial, optical glass, high purity), niobium carbide, lithium niobate single crystal, niobium and its alloy superconducting materials, etc.
Tantalum powder and tantalum wire are the key materials for making tantalum capacitors. Widely used in mobile phones, computers, digital products, automotive and aerospace electronics and other fields, about 60% of the world's tantalum used in the manufacture of tantalum capacitors. Tantalum and niobium target material for semiconductor devices and liquid crystal display technology, niobium oxide, niobium and niobium powder, niobium wire used in the manufacture of ceramic capacitor capacitor, niobium wire is mainly used for production of high strength low alloy steel, stainless steel, heat-resistant steel, clearance steel, carbon steel, tool steel, rail steel, cast steel, about 90% of the world's niobium used in iron and steel industry. Tantalum or niobium can be added into tungsten, molybdenum, nickel, cobalt, vanadium, iron base alloy or other metal elements based on tantalum or niobium to produce superalloy, which is an important structural material for aerospace engines, land-based airflow turbine engines, modern weapons and facilities in harsh industrial environment. Tools such as cutting tools and drilling tools made of tantalum carbide, niobium carbide and other hard alloys can withstand a high temperature of nearly 3000℃, and their hardness is comparable to that of diamond. Because niobium and tantalum have good superconductivity, adding niobium and tantalum into the materials of wire and cable can greatly reduce the loss of electric energy, thus saving electric energy. Tantalum niobium is a kind of high quality material which can resist acid and liquid metal corrosion. In addition, tantalum niobium and its alloys can also be used as nuclear reactor cladding materials and high energy physics superconducting devices. At the same time, tantalum is an ideal biological adaptability material and is widely used in medical surgery.
