Consumption of tantalum increased significantly in the second half of the 1990s with the demand for capacitors required for products in the rapidly growing consumer electronics market. Tantalum is the third most refractory metal, only after tungsten and rhenium, with a melting point of 2980 ℃, element symbol Ta, atomic number 73, and a density of 16.68g / cm³. Other applications Tantalum is used in a range of other applications requiring strength, ductility, toughness, corrosion resistance, thermal conductivity and high melting point: Tantalum compounds for optical applications and surface acoustic wave filters. Blanking or punching presents no difficulties. Another major use of tantalum is for electronic components, and due to its absorption properties, tantalum is an excellent getter of residual gasses in evacuation tubes. Unfortunately for Ekeberg, in 1809 the well-known English chemist Willian Wollaston said there had been no discovery and there was no new element. Properties, SDS, Applications, Price. Free samples program. Tantalum has a series of excellent properties such as high melting point, low vapor pressure, good cold workability, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of the oxide film on the surface.

Tantalum was discovered by Anders G. Ekeberg in 1802, in Uppsala, Sweden, in the minerals tantalite from Finland and yttrotantalite from Sweden. In 1802, the Swedish chemist A.G. Ekaberg (1767-1813) discovered new elements while analyzing niobium-tantalite ore from Scandinavia. If the piece is going to be drawn in One operation, a draw of which the depth is equal to the diameter of the blank can be made. It can be drawn into a fine wire that is used to evaporate metals, such as aluminum. Globally proven tantalum resources are mainly distributed in Australia and Brazil. Tantalum has excellent corrosion resistance to most chemicals except hydrofluoric acid. About Tantalum (Ta) Tantalum is a lustrous, blue-gray, ductile, hard metal that is highly resistant to corrosion. Tantalum(V) alkoxides typically exist as dimers with octahedral six-coordinate tantalum metal centres. Tantalum metal has a melting point exceeded only by tungsten & rhenium. The aerospace and nuclear industries have found a variety of applications for the metal. Among them, Rwanda’s production accounts for half of the global production. The melting point of tantalum is approximately 3017 degrees Celsius. Tantalum Metal Ta bulk & research qty manufacturer. Advantages And Disadvantages Of Titanium Used in Automobile Industry. TANTALUM metal bullion bar - ingot - 48.2 grams This one is a bit lighter with 45.2 grams which is correctly engraved (on the picture there is a 48.5 gram one) Purity: 99.95% Size: 38 x 22 x 3 mm Laser engraved (The engraving can be changed to customers request) What Are the Special Applications of Iridium Alloy? Tantalum is a ductile metal. Tantalum is used in light bulb filaments. The secondary resources of niobium tantalum include two parts: one part is the waste generated during the smelting and processing of niobium-tantalum, and the other part is the components and parts scrapped during the use of niobium-tantalum products. The United States, Burundi, Canada, Congo (DRC), Ethiopia, Mozambique, Nigeria, and Rwanda all have tantalum resources, but the exact amount is uncertain. Tantalum was discovered by the Swedish chemist Anders Ekeberg, who extracted the metal from mineral samples. Subsequent crystallographic analysis established that the methoxide and isopropoxides of niobium adopt bioctahedral structures. The tantalum supply chain can be relatively lengthy in terms of raw material traceability. In spite of being a relatively scarce metal, tantalum is one of the most technologically important materials in the world due to the essential role it plays in electronics, biomedical devices, superalloys, and corrosion-resistant coatings. Back to home page Return to top. Tantalum electrolytic capacitors exploit the tendency of tantalum to form a non-conductive protective oxide surface layer. Tantalum is a very dense, malleable metal making it easy to work with similar to gold. Today, the market for tantalum is supported by the growth in consumer electronics, aerospace, medical, military, energy and chemical processing. Using the physical vapor deposition (PVD) process, tantalum is “sputtered” onto semiconductor substrates to form a thin film diffusion barrier to protect the copper interconnects. It has a rich slate bluish-gray color. What Refractory Metals Are Commonly Used in Vacuum Systems? Wollaston claimed Ekebergâs new element was actually niobium, which had also been discovered in 1802. Its why it is ideal for mobile phones, personal computers, DVD players, video game systems, ⦠Chemical processing equipment Tantalum’s high resistance to corrosion and high temperature makes the metal an ideal material of construction for liners in vessels, piping, valves and heat exchangers in the chemical and pharmaceutical industries. Engine turbine blades The metal’s high melting point and resistance to corrosion makes it suitable for alloying applications. In terms of efficiency and dependability, tantalum is better than plastic. Tantalum sputtering targets are used in a variety of other products, including magnetic storage media, inkjet printer heads and flat panel displays. Another use is chemical process equipment such as heat exchangers and condensers. But the main and most important function of the metal is in the manufacture of electrolytic capacitors for the electronics industry. Refinery items used as feed for our process input include Tantalum residues, slags, sludges, off spec Tantalum powders and highly contaminated Tantalum turnings and solids. The clearance between the punch and die should be close to 6% of the thickness of the metal being worked. Steel dies are used. Tantalum and niobium wastes, such as compounds and alloys, have many types and complex compositions, so various recycling processes have been developed. Tantalum is a metallic element with a bluish tint and excellent ductility. The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride. A very hard metal that is very rare and used in high temp productions such as the space industry. Tantalum is a strong, ductile metal that is nearly immune to chemical attack at room temperatures. According to data released by the US Geological Survey (USGS) in 2015, the global reserves of tantalum resources exceeded 100,000 tons, including 67,000 tons in Australia and 36,000 tons in Brazil. As the market moves to greater miniaturization, the tantalum capacitor is favored in space-sensitive, high-end applications in telecommunications, data storage and implantable medical devices. Tantalum is a soft, ductile, grey-blue metal with a high melting point. Tantalum, a highly biocompatible metal, has been shown to be safe to use in biomedical applications and is excreted in the urine. According to the type of waste materials, tantalum niobium waste materials mainly include pure metals, compounds, and alloys. Its physical properties make it ideal for numerous applications, particularly in the electronics and aerospace industries. This results in high capacitance in a very small volume, which give the product size and weight benefits. GAM assures customers that the source of their raw materials can be traced. He named the element Tantalum after Tantalus, the son of Zeus in Greek mythology. Pure metal waste is generally recovered by vacuum smelting, electron beam smelting, and hydrogenation powder smelting after chemical cleaning. Additive manufacturing Tantalum offers a high corrosion resistance, high strength and high purity, which enables 3D printing of parts for the aerospace, automotive, medical, defense, energy and chemical processing industries. Term contracts & credit cards/PayPal accepted. Two large pieces of 99.999% pure tantalum one weighing 34g the other weighing 33g. Metal/Alloy Type: Tantalum. Australia alone accounts for nearly 62% of global tantalum reserves, followed by Brazil, which accounts for 36% of the total. Tantalum can be printed utilizing any of the common printing technologies like laser powder bed fusion, electron beam, direct energy deposition, Binderjet and MIM. Tantalum can be found in capacitor form from electronic equipment and can be analyzed at Rockaway Recycling, just ask. Tantalumâs most common use is in electrolytic capacitors. The concentrate is also used to produce pure tantalum pentoxide (Ta2O5) primarily utilized in the production of optical glass and lithium niobate. The principal source of tantalum until the 1990s was tin mining, where tantalum was extracted as a by-product. Occasionally used for rare pieces of medical equipment or instruments as well.
