Tantalum metal introduction

                         Tantalum metal introduction

   Tantalum has a wide range of applications due to its many bizarre properties , therefore, is known as a "versatile metal kingdom."
Tantalum is very hard texture, hardness of 6-6.5 (diamond is 10), its melting point up to 2996 ℃, second only to tungsten and rhenium, ranking the third place of all elements. Tantalum is malleable and can be drawn into thin or thin foil. Its coefficient of thermal expansion is small, with each increase of 1 ° C only swells 6.6ppm. In addition, it is very tough and superior to copper. Tantalum also has a very high corrosion resistance. Whether it is hot and cold conditions, hydrochloric acid, concentrated nitric acid and "aqua regia" (gold will encounter king of water will melt) will not respond. Tantalum will be immersed in sulfuric acid at 200 ℃ for one year, the surface damage only 0.006mm.
   The application of tantalum, the pioneer of war machines and technology Tantalum has the characteristics that make it a very broad field of application, can be divided into the following major items:
 (1) In the aerospace industry: the manufacture of jet aircraft, Spacecraft, rocket engine components such as combustion chambers, combustion ducts, turbo pumps, rocket launchers, spacecraft propulsion and afterburner valves. At the same time, tantalum is also a good structural material for jet aircraft, rockets and missiles and is commonly used to make fairings.
 (2)  Tantalum in the military industry: The production of armor-piercing linings, which is currently mainly used in the United States, is famous for its use of tantalum anti-tank missiles.
 (3) Tantalum is used to make tantalum capacitors: tantalum powder and tantalum wire are the key materials for making tantalum capacitors. Tantalum capacitors are the best capacitors used in radar, missiles, computers, and automotive electronics. This is also the largest part of tantalum production.
 (4) High temperature tantalum products:Tantalum plate,tantalum tube,etc. tantalum high temperature resistance, strength and stiffness is good, is the production of high-temperature vacuum furnace heating components, insulation components and high-quality materials, containers.
(5) Tantalum is used to make corrosion-resistant products: Tantalum is a material that is excellent in acid and alkali resistance and liquid metal corrosion and can be used in the chemical industry to make utensils such as digesters, heaters, coolers and crucibles.
(6) tantalum carbide for carbide additives: Carbide is mainly used for tools, tools, molds and wear-resistant corrosion-resistant structural components, adding tantalum carbide can improve its hardness, strength, melting point and other properties.
(7) Tantalum oxide and niobium oxide are raw materials for manufacturing tantalum niobium artificial crystals: tantalum pentoxide and niobium pentoxide are raw materials for manufacturing LT, LN and other crystals. LT and LN are important piezoelectric, thermoelectric and nonlinear optical Materials have important applications in the technical fields of atomic energy, lasers and microphones.
 (8) Other Applications: Tantalum Cathode sputtering targets, high vacuum suction pump tantalum active material, tantalum pentoxide, niobium pentoxide as optical glass modifier and chemical catalyst in the medical tantalum metal can be used as human ( Bones, nerves) repair materials, good affinity for the human body structure.
