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. Tantalum is a shiny, silvery metal which is soft when is pure. Tantalum is a greyish-blue transition metal. Tantalum metal has a melting point exceeded only by tungsten & rhenium. Tantalum has excellent corrosion resistance to most chemicals except hydrofluoric acid. Tantalum in its natural form is a dense mineral highly moldable by heat or electricity, making it an optimal choice for industrial usage. It is very inert and so useful in the chemical and nuclear industries to line reactors. 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 (Ta) capacitors and multilayer ceramic capacitors (MLCCs) are two widely accepted capacitor technologies that can be employed in a wide range of electronics applications. Due to its strength and utilitarian appeal, tantalum is a popular metal used in jewelry pieces including tantalum rings and bands, and watches. Applications. It is an efficient conductor or electricity and heat. More than 60 percent of this mined element is used to make capacitors for cellphones, pagers, personal computers, video cameras and automotive electronics. 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. The periodic table is a chart that shows how chemical elements are related to one another. Tantalum combines readily with other refractory metals, such as tungsten, to form alloys with high-temperature strength and stability. Tantalum compounds are used in the special glass used in camera lenses. Tantalum is a strong, ductile metal that is nearly immune to chemical attack at room temperatures. A very hard metal that is very rare and used in high temp productions such as the space industry. Occasionally used for rare pieces of medical equipment or instruments as well.
