Tantalum is a chemical element; it has symbol Ta and atomic number 73. It is named after Tantalus, a figure in Greek mythology. [11] Tantalum is a very hard, ductile, lustrous, blue-gray transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as components of strong high-melting ...
Tantalum electrolytic capacitors are extensively used in electronic devices that require stable capacitance, low leakage current, and where reliability is crucial. [1] Due to its reliability, durability and performance under extreme conditions, it is used in medical equipment, [2] aerospace and military applications. [3]
It has been suggested that titanium's capacity for osseointegration stems from the high dielectric constant of its surface oxide, which does not denature proteins (like tantalum, and cobalt alloys). [3] Its ability to physically bond with bone gives titanium an advantage over other materials that require the use of an adhesive to remain attached.
Natural tantalum (73 Ta) consists of two stable isotopes: 181 Ta (99.988%) and 180m Ta (0.012%).. There are also 35 known artificial radioisotopes, the longest-lived of which are 179 Ta with a half-life of 1.82 years, 182 Ta with a half-life of 114.43 days, 183 Ta with a half-life of 5.1 days, and 177 Ta with a half-life of 56.56 hours.
Tantalum is one of the most corrosion-resistant substances available. Many important uses have been found for tantalum owing to this property, particularly in the medical and surgical fields, and also in harsh acidic environments. It is also used to make superior electrolytic capacitors.
Metals in medicine are used in organic systems for diagnostic and treatment purposes. [1] Inorganic elements are also essential for organic life as cofactors in enzymes called metalloproteins . When metals are under or over-abundant in the body, equilibrium must be returned to its natural state via interventional and natural methods.
Radioactive isotopes are used in medicine for both treatment and diagnostic scans. The most common isotope used in diagnostic scans is Technetium-99m, used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems ...
TAV-ELI is the most commonly used medical implant-grade titanium alloy. [29] [31] Due to its excellent biocompatibility, corrosion resistance, fatigue resistance, and low modulus of elasticity, which closely matches human bone, [32] TAV-ELI is the most commonly used medical implant-grade titanium alloy.
