Tantalum
Key words:
Tantalum and niobium, also known as tantalum and niobium alloy, is an important metal material, which is composed of two metal elements, tantalum and niobium. Tantalum niobium has excellent mechanical properties and corrosion resistance, widely used in aerospace, chemical, electronics, medical and other fields.

Development direction of tantalum and niobium market
China's tantalum and niobium industry started in the 1950 s. After years of development, it has gradually established a relatively complete industrial system with independent intellectual property rights from mining, mineral processing, smelting, processing to application. In recent years, Chinese tantalum and niobium enterprises have been determined to forge ahead, go abroad, participate in international market competition, and steadily embark on the road of industrialization, informatization, internationalization and capitalization. China's tantalum and niobium industry has made great progress and development in the modernization of enterprise management, production scale and R & D level, comprehensive utilization of tantalum and niobium resources, comprehensive environmental management, occupational health protection and safe production, international operation, capital operation and so on.

What are the ore types of tantalum-niobium deposits?
Tantalum-niobium deposits can be divided into five categories according to their genesis: magmatic deposits, Weijing deposits, vapor-forming hydrothermal deposits, contact self-metamorphic deposits and exogenous deposits. The tantalum and niobium minerals with industrial value mainly include tantalite, niobium iron ore, yellow chlore, brown yttrium niobium ore, black rare earth ore, titanium niobium calcium cerium ore, equiaxed tantalum lime stone, uranium tantalum niobium ore, fine stone, easy solution stone, etc. The size of tantalum-niobium deposits formed by ore-bearing rocks of different deposit types varies greatly.

Properties and Uses of Tantalum and Niobium
Tantalum (Ta) and niobium (Nb) are rare metals with high melting point (tantalum 2996 ℃, niobium 2468 ℃) and high boiling point (tantalum 5427 ℃, niobium 5127 ℃). The density of tantalum is 16.65g/cm³; The density of niobium is 8.57g/cm³. The appearance is like steel, gray white luster, powder is dark gray, with suction, corrosion resistance, superconductivity, unipolar conductivity and high strength at high temperature.
