Tantalun Products
Characteristic of Tantalum:
Tantalum is a rare,hard and blue gray metal that is highly corrosion resistant.it is widly used as monor component in alloys,tantalum capacitors in electronic equipments such as mobile phones,DVD players and computers.Tantalum is always together with the chemically similar niobium and occurs in the minerals tantalite.
Products Manufacturing:
Under hydrogen reduction process, tantalum ore is reduced into powder. after screening and homogenization tantalum powder is pressed into rods and plates of various geometries and dimensions. In hydrogen furnaces sintering takes place. The mechanical strength and density of the pressed compact increase during the sintering process to reach the properties necessary for further processing to semi-finished products.
The sintered billets are hot worked at temperatures in the range 1200-1500 using process such as extrusion, forging, rolling. As the deformation increases the working temperature can be reduced. In this way forged parts, round bars, sheets, foils and ribbons are made. Wires are produced from the round bars by drawing.
Applications of Tantalum:
About half of the world's tantalum metal is used in the electronics industry to manufacture tantalum capacitors in electronic equipments, like DVD player, mobile phone, Laptop, and digital cameras and electronic systems for vehicles. and circuit board connectors because of its size and weight advantage.
Tantalum is also used as an alloy additive in nickel based superalloys in the manufacture of turbine blades for the aerospace industry and land based gas turbines. Alloyed with other metals, it is also used ub making carbide for metalworking equipments, nuclear reactors and missile parts. Tantalum, because of its ductility, can be drawn into tantalum wire or tantalum filaments, tantalum sheet and tantalum rod.
Tantalum have highly corrosion resistant for acids except hydrofluoric acid and hot sulfuric acid. So this advantage makes it idea material for the chemical reaction vessels and tubes.
Other uses include sputtering targets, mill products, cutting tools, surgical implants and specialty chemicals and coatings.
Tantalum Capacitors:
Tantalum powder and Tantalum wire are used to make tantalum capacitors. until now tantalum capacitors are the most excellent one in the world
High-temperature tantalum products:
Tantalum has good work ability under high temperature and high hardness and good inflexibility.tantalum is best choice for heat parts, heat insulation parts and load vessels in cacuum high temperature furnace.
Erosion-resistant Tantalum products:
Tantalum and Niobium material are highly resistant to acid or alkali and also liquid metals. So Tantalum and Niobium products like tantalum rod, tantalum sheet,tantalum wire and tantalum crucible can be used to make boiler, heater, cooler, etc., in chemical industry.
Aerospace industry:
Tantalum is used to make airplane engines, such as firebox, burning-vessel and turbine pump for aeroplane, rocket, submarine, etc
Tantalum Products:
Tantalum and tantalum alloy:
Pure tantalum, tantalum-2.5% tungsten alloy, tantalum-10% tungsten alloy, tantalum-hafnium alloy, etc
