Tantalum finds use in four areas: high-temperature applications, such as aircraft engines; electrical devices, such as capacitors; sirurgical impants and handling corrosive chemicals. What is Tantalum? It is very inert and so useful in the chemical and nuclear industries to line reactors. The melting point of tantalum is approximately 3017 degrees Celsius. Tantalum is a greyish-blue transition metal. 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. Symbol: Ta; atomic weight: 180.948; atomic number: 73; specific gravity: 16.6. Because of its hardness and corrosion resistance, it is an important refractory metal and is … Tantalum is extensively used in products that require high reliability in extreme environments. Instead, it is typically found in the ore columbite-tantalite (usually referred to as coltan). A high-performance tantalum capacitor offers designers a reliable and stable high-capacitance solution. Occasionally used for rare pieces of medical equipment or instruments as well. These find use in aircraft and missile manufacture. Raw tantalum rarely occurs in nature. 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 (Ta) is a black-gray metal, number 73 in the Periodic Table of Elements. Tantalum is a strong, ductile metal that is nearly immune to chemical attack at room temperatures. Its melting point can reach 2996 ℃, which is second only to tungsten and rhenium. See more. Tantalum metal has a melting point exceeded only by tungsten & rhenium. It is hard and shiny in nature. Tantalum has the atomic number 73, snuggling the element between hafnium, niobium, and tungsten in the transition metal section of the periodic table. Tantalum is found in a combination of rare minerals and is grey-white in color. Biological Benefits Tantalum (Ta) is an unsung hero in modern metallurgy. Tantalum is used in widely used to create electronic parts such as capacitors and high-power resistors among other things. 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. It is common practice to name any mineral concentrate containing tantalum as tantalite. Extremely rare, the primary resources of tantalum could potentially be exhausted within the next fifty years. Tantalum combines readily with other refractory metals, such as tungsten, to form alloys with high-temperature strength and stability. 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. It has a high melting point and is frequently used as a substitute for platinum , which is more expensive. 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 is a ductile highly resilient metallic chemical element with the chemical symbol Ta and an atomic number of 73. 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. Tantalum’s unique physical and chemical properties are expected to ensure high usage in new technologies and has been in our materials since the early 1800’s. First discovered by the Swedish chemist Anders Ekeberg in 1802, this versatile metal has become essential to numerous industries over the years. Titanium is also known as corrosion resistant metal. Tantalum metal has a number of important uses. Tantalum is naturally grayish in color with a hint of blue. Tantalum is alloyed with steel to increase steel's ductility, strength and melting point. Unfortunately for Ekeberg, in 1809 the well-known English chemist Willian Wollaston said there had been no discovery and there was no new element. An inert material is one that does not react with most other chemicals. Tantalum appears as a shiny and silvery metal in its soft and pure form. Its name originates from the name of a villain from Greek mythology, Tantalus. It is an efficient conductor or electricity and heat. 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. It can be drawn into a fine wire that is used to evaporate metals, such as aluminum . Tantalum is a very dense, malleable metal making it easy to work with similar to gold. Tantalum is an element on the periodic table and is considered a technology critical material. 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. Tantalum (Ta) is a refractory, acid resistant, ductile and easily fabricated metal with a high melting temperature (2,996° Celsius). The use of tantalum in the capacitor allows for a … 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. Tantalum is ductile and can be fabricated for various purposes . It has a rich slate bluish-gray color. 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. Tantalum metal can easily fabricated and It is a … According to the United States Geological Survey, tantalum's major use is in the production of electronic components.
