Tantalum (Ta) and niobium (Nb) both have high melting points (tantalum 2996°C, niobium 2468°C) and high boiling points (tantalum 5427°C, niobium 5127°C). They look like steel, with off-white luster, and the powder is dark gray.
Therefore, the current high-tech industries related to the application of tantalum and niobium new materials include electronics, precision ceramics and precision glass industries; electroacoustic and optical devices; cemented carbide, aerospace and electronic energy industries; biomedical engineering; superconducting industry; special steel, etc. industry.
Tantalum and niobium play a very important role in the electronic industry, chemical industry, special alloys, vacuum technology, and cutting-edge technology. In the electronics industry, electrolytic capacitors made of tantalum metal have outstanding characteristics such as large capacitance, small leakage current, good stability, high reliability, good voltage resistance, long life, and small size. It is widely used in electronic circuits of national defense, aviation, aerospace, electronic computers, high-end civilian appliances and various electronic instruments.
In the metallurgical industry, tantalum and niobium are mainly used as additives to produce high-strength alloy steel, improve the properties of various alloys, and make super-hard tools.
