Tantalum is a rare, silvery-gray metal that is highly resistant to corrosion and has many uses in industrial applications. It has a unique combination of physical and chemical properties, making it an essential component of modern manufacturing processes. Let’s take a closer look at some of the more interesting aspects of tantalum.
Tantalum Chemical Composition
Tantalum is part of the transition group of elements on the periodic table, and its chemical symbol is Ta. Its atomic number is 73, with an atomic mass of 180.9479 AMU (atomic mass units). It has five naturally occurring isotopes, including tantalum-180, -181, -182, -183, and -184. Its oxidizing state is +5, and its boiling point is 5731°F (3155°C).
Tantalum Color & Hardness
Tantalum generally has a grayish hue but can be polished to produce other hues, such as silver or light blue. It is one of the hardest metals known to man, with a Mohs hardness rating between 8-9. This makes it helpful in creating items such as cutting tools due to its resistance to wear and tear over time.
Tantalum Physical Properties
Tantalum melts at a temperature of 2980°C (5376°F), which makes it relatively difficult to work with compared to other metals like steel or iron, which melt at much lower temperatures. Tantalum also has excellent electrical conductivity properties and good thermal stability when exposed to high temperatures. It is useful for applications requiring heat resistance, such as aerospace or automotive manufacturing processes. Additionally, tantalum maintains its strength even when exposed to low temperatures, which makes it ideal for cryogenic applications due to its low-temperature resistance qualities.
Atomic Number
The atomic number of tantalum is 73. This means there are 73 protons in the nucleus of every tantalum atom.
Atomic Mass
The atomic mass of tantalum is 180.948 u. This is the mass of one atom of tantalum, expressed in atomic mass units.
Melting Point
The melting point of tantalum is 2996 degrees Celsius. This is the temperature at which a solid tantalum sample will begin to melt.
Boiling Point
The boiling point of tantalum is 5425 degrees Celsius. This is the temperature at which a liquid tantalum sample will begin to boil.
Density
The density of tantalum is 16.69 grams per cubic centimeter. This is the amount of mass that is contained in one cubic centimeter of tantalum.
Tantalum Chemical Properties
Tantalum, a chemical element in the periodic table, has fascinating properties and is used in various ways across many industries. Its unique atomic structure gives it high strength, which makes tantalum ideal for aerospace engineering and technological applications. This metal also has high melting and boiling points, making it resistant to corrosion by acids, alkalis, and other corrosive materials. A particularly intriguing property of tantalum is its ability to store many electrical energy thanks to its low dielectric losses; this makes it ideal for capacitors and mobile phone batteries. Most remarkably, when combined with other elements, tantalum can become superconducting at temperatures as cold as 4 degrees Kelvin (or -269 Celsius). With such incredible properties, it’s no wonder tantalum is so widely used worldwide today!
