Tantalum (Ta) niobium (Nb) is a rare metal with high melting point (tantalum 2996℃, niobium 2468℃), high boiling point (tantalum 5427℃, niobium 5127℃), the appearance is like steel, gray luster, powder is dark gray, has the characteristics of inhalation, corrosion resistance, superconductivity, unipolar conductivity and high strength at high temperature.
Therefore, the current applications of tantalum niobium new materials related to the high-tech industries include electronics, precision ceramics and precision glass industry; Electro-acoustooptic device; Cemented carbide, aerospace and electronic energy industry; Biomedical engineering; Superconducting industry; Special steel and other industries.
Tantalum and niobium are very important in electronic industry, chemical industry, special alloy, vacuum technology and advanced technology. Electrolytic capacitors made of tantalum in the electronics industry are characterized by large capacitance, small leakage current, good stability, high reliability, good voltage resistance, long life and small volume. A large number of national defense, aviation, aerospace, electronic computers, high-grade civil electrical appliances and all kinds of electronic instruments in the electronic circuit.
In the metallurgical industry, tantalum niobium is mainly used as an additive to produce high strength alloy steel, improve the properties of various alloys and make superhard tools.
