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.
Equipment such as medical electronics and space equipment that require high quality and reliability makes use of tantalum capacitors. An especially common application for low-voltage tantalum capacitors is power supply filtering on computer motherboards and in peripherals, due to their small size and long-term reliability.
Coltan is used primarily for the production of tantalum capacitors, used in mobile phones and almost every kind of electronic device. [ 31 ] [ 32 ] [ 33 ] Niobium and tantalum have a wide range of uses, including refractive lenses for glasses, cameras, phones and printers.
ECRI called gaps with recalls of home-use medical devices “the nation’s most pressing health technology safety issue for 2023.” The researchers wrote: “Accurate and understandable ...
Treatment of tantalum pentachloride with hexamethylbenzene (C 6 Me 6), aluminium, and aluminium trichloride gives [M(η 6-C 6 Me 6)AlCl 4] 2. [7] Tantalum-alkyne complexes [8] catalyze cyclotrimerizations. [9] [10] Some tantalum-alkyne complexes are precursors to allylic alcohols. [11] Tantalacyclopropenes are invoked as intermediates.
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.
Medical halogen penlight: to see into the eye, natural orifices, etc. and to test for pupillary light reflex, etc. Medical ultrasound: to create an image of internal body structures Nasogastric tube: for nasogastric suction or the introduction of food or drugs into the body Nebulizer: to produce aerosols of drugs to be administered by ...
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.
