Tantalum (Ta) is a black-gray metal, number 73 in the Periodic Table of Elements. Tantalum often plays the role of protecting other metals, whether the tantalum is used in a thin coating to protect its substrate from chemical attack, or as an additive in superalloys to improve their high-temperature performance. Because of its hardness and corrosion resistance, it is an important refractory metal and is … Wollaston claimed Ekeberg’s new element was actually niobium, which had also been discovered in 1802. Tantalum metal has a number of important uses. Tantalum was discovered by Anders G. Ekeberg in 1802, in Uppsala, Sweden, in the minerals tantalite from Finland and yttrotantalite from Sweden. Tantalum is resistant to corrosion. The tantalum capacitor consists of a small pellet of tantalum which acts as the anode for the capacitor. Tantalum is a dense metal, with a density of 7.98 g/cm3. Tantalum, a lesser known element on the periodic table, is best known for being one of the most corrosion resistant and inert metals on earth, even surpassing gold. Titanium is also known as corrosion resistant metal. Tantalum is a rare metal that takes up about 2 ppm of the earth’s crust, it is hard and it is highly resistant to corrosion. Its name originates from the name of a villain from Greek mythology, Tantalus. Tantalum is a shiny, silvery metal which is soft when is pure. It is very inert and so useful in the chemical and nuclear industries to line reactors. Tantalum is alloyed with steel to increase steel's ductility, strength and melting point. Tantalum is a strong, ductile metal that is nearly immune to chemical attack at room temperatures. Tantalum appears as a shiny and silvery metal in its soft and pure form. According to the United States Geological Survey, tantalum's major use is in the production of electronic components. An inert material is one that does not react with most other chemicals. Tantalum (Ta) capacitors and multilayer ceramic capacitors (MLCCs) are two widely accepted capacitor technologies that can be employed in a wide range of electronics applications. Tantalum metal has a melting point exceeded only by tungsten & rhenium. The only metal which burns in Nitrogen is Titanium. the melting and boiling points … Applications. Tantalum metal can easily fabricated and It is a … These find use in aircraft and missile manufacture. Major Uses Tantalite, or coltan, is a key component in the building of electronic capacitors, which without this mineral, many electronic devices around the world would stop. Unfortunately for Ekeberg, in 1809 the well-known English chemist Willian Wollaston said there had been no discovery and there was no new element. It is almost immune to chemical attack at temperatures below 150 C. Tantalum is virtually resistant to corrosion due to an oxide film on its surface. More than half of the world’s tantalum is mined in Africa, including artisanal It is used to make steels with desirable properties such as high melting point, high strength, good ductility. It’s where tantalum and niobium come from The mineral coltan is one of the resources that is playing an important role in the technological revolution. Occasionally used for rare pieces of medical equipment or instruments as well. See more. Tantalum minerals have more than 70 different chemical compositions, of which tantalite [(Fe,Mn)Ta 2 O 6], microlite (CaTa 2 O 6), and wodginite [Mn(Sn,Ta)(Ta,Nb) 2 O 8] are of greatest economic importance. Symbol: Ta; atomic weight: 180.948; atomic number: 73; specific gravity: 16.6. It is hard and shiny in nature. A very hard metal that is very rare and used in high temp productions such as the space industry. Tantalum can be found in capacitor form from electronic equipment and can be analyzed at Rockaway Recycling, just ask. Tantalum definition, a gray, hard, rare, metallic element occurring in columbite and tantalite and usually associated with niobium: used, because of its resistance to corrosion by most acids, for chemical, dental, and surgical instruments and apparatus. Tantalum’s ability to grow a thin continuou… First discovered by the Swedish chemist Anders Ekeberg in 1802, this versatile metal has become essential to numerous industries over the years. Due to its extraordinary ability to withstand heat and physical stress, tantalum is considered a refractory metal and have been widely used along with other refractory group elements, including platinum etc. It is an efficient conductor or electricity and heat. The metal is commonly found in capacitors and super alloys that are applied in many electronics, automotive and aerospace products. It has a rich slate bluish-gray color. With nearly 60 years of utilization, Tantalum capacitors are employed in developing various applications for industries like military and commercial avionics, industrial automation and control systems, critical and implantable medical electronics, smartphones, laptops, desktops, and … Its melting point can reach 2996 ℃, which is second only to tungsten and rhenium. Tantalum is naturally grayish in color with a hint of blue. Tantalum is a blue-gray transition metal with element symbol Ta and atomic number 73. Tantalum also does not irritate the body and is used to make surgical sutures as well as implants, such as artificial joints and cranial plates. Extremely rare, the primary resources of tantalum could potentially be exhausted within the next fifty years. It has a high melting point and is frequently used as a substitute for platinum , which is more expensive. Tantalum is a very dense, malleable metal making it easy to work with similar to gold. Tantalum combines readily with other refractory metals, such as tungsten, to form alloys with high-temperature strength and stability. Instead, it is typically found in the ore columbite-tantalite (usually referred to as coltan). Tantalum is an element on the periodic table and is considered a technology critical material. Tantalum in its natural form is a dense mineral highly moldable by heat or electricity, making it an optimal choice for industrial usage. Tantalum is a transition metal in Group 5 (VB) of the periodic table. A high-performance tantalum capacitor offers designers a reliable and stable high-capacitance solution. This is covered by a layer of oxide which acts as the dielectric for the capacitor and in turn this is surrounded by a conductive cathode. Tantalum (atomic number 73, symbol Ta) is a hard, heavy metal that is grayish silver in color.The element was discovered by the Swedish chemist Anders Ekeberg in 1802 while Christian Blomstrand proved that niobium and tantalum are different elements in 1864. It can be drawn into a fine wire that is used to evaporate metals, such as aluminum . Tantalum is a chemical element with symbol Ta and atomic number 73 in the periodic table. The melting point of tantalum is approximately 3017 degrees Celsius. Raw tantalum rarely occurs in nature. Tantalum capacitors are found in smartphones, tablets, and computers. More than 60 percent of this mined element is used to make capacitors for cellphones, pagers, personal computers, video cameras and automotive electronics. As the natural sources of tantalum are quickly depleting, experts believe that only about 50 years’ worth of … Due to its strength and utilitarian appeal, tantalum is a popular metal used in jewelry pieces including tantalum rings and bands, and watches. Tantalum is a ductile metal. Tantalum is a kind of refractory nonferrous metal with a hardness of 6-6.5. What is Tantalum? Tantalum is extensively used in products that require high reliability in extreme environments. Tantalum has excellent corrosion resistance to most chemicals except hydrofluoric acid. Tantalum alloys are used in a variety of high-stress applications, such as nuclear reactors, cutting tools, missiles, aircraft and chemical processing equipment. Biological Benefits Tantalum is largely corrosion resistant and used extensively to … Tantalum (Ta) is an unsung hero in modern metallurgy. Tantalum is found in a combination of rare minerals and is grey-white in color. Tantalum is a greyish-blue transition metal.
