Metal tantalum, tantalum rod, tantalum belt, tantalum powder and tantalum Article 

 Long-term supply of imports of the metal tantalum, tantalum rod, tantalum belt, tantalum powder and bar, symbol: Ta; color: dark gray; boiling point: 5458, Tantalum is a rare metal was steel gray luster, melting point up to 2980 ℃, the density of 16.6 g / cm 3. Tantalum and niobium are similar in nature, is a very stable chemical elements. React with tantalum, only fluoride, hydrofluoric acid, fluoride ions in acid solution and sulfur trioxide. At room temperature reaction with concentrated alkali solution, and dissolved in molten alkali. Dense tantalum began slightly oxidized at 200 ℃. Good low-temperature plasticity of tantalum, tantalum-based alloys even at -196 ℃ but also to maintain scalability. Tantalum also has additional absorption of hydrogen, nitrogen, ability, and is under suction at 200-300 ℃, high temperature 800-1200 ℃ under vacuum and re-precipitation. Under natural conditions, tantalum, niobium and more for the symbiosis, including tantalum, niobium minerals are: iron ore of tantalum and niobium and tantalum and niobium salts containing placer. Tantalum Tin Smelting Slag is also an important resource extraction. Tantalum or niobium mine by mine owners to look at minerals containing tantalum or niobium number may be.
