Tantalum has a number of interesting properties that make it particularly useful in 

electronic applications. It has the third highest melting point, surpassed only by 

rhenium and tungsten, yet it is highly conductive to heat and electricity. This has 

made it the material of choice for the electronic capacitors used in most 

telecommunications and hand held electronics equipment, such as cell phones, 

laptop computers and pagers. Tantalum compounds, such as tantalum oxide and 

tantalum chloride, are the basis for dielectric coatings. High Purity (99.999%) 

Tantalum Oxide (Ta2O5) PowderTantalum is added to glass for its high refractive 

index. It also has various applications in nuclear energy. 

Tantalum is available as metal and compounds with purities from 99% to 99.999% 

(ACS grade to ultra-high purity). Elemental or metallic forms include tamtalum 

pellets, rod, wire and granules for evaporation source material purposes. High 

Purity (99.999%) Tantalum Sputtering Target Tantalum nanoparticles and 

nanopowders provide ultra-high surface area which nanotechnology research and 

recent experiments demonstrate function to create new and unique properties and 

benefits. Oxides are available in powder and dense pellet form for such uses as 

optical coating and  thin film applications. Oxides tend to be insoluble. Fluorides 

are another insoluble form for uses in which oxygen is undesirable such as 

metallurgy, chemical and physical vapor deposition and in some optical coatings. 

Tantalum is also available in soluble forms including chloride, nitrate, and acetate. 

These compounds can be manufactured as solutions at specified stoichiometries.
