Tantalum Pentoxide | High Purity Materials

Tantalum pentoxide powder Ta2O5 has been developed by ALB Materials for the capacitor, optical, glass, and ceramic applications.

Tantalum pentoxide also called tantalum has the chemical formula Ta2O5.

Tantalum pentoxide has a dielectric coefficient (K) of 25-100 and a refractive index of 2.27, which is used in anti-reflection coatings in optical lenses, charge capacitors in DRAM devices, low voltage organic thin-film transistors and in “gate” dielectric applications.

As the source of Ta2O5, the tantalum element is in the fifty-fourth place in terms of availability in the earth.

The most important minerals containing tantalum are tantalite – (Fe, Mn) Ta2O6, vodginite – (Ta, Nb, Sn, Mn, Fe) 16O32, microlite – (Na, Ca)(Ta, Nb)2O6F and columbite – (Fe, Mn)(Nb, Ta)2O6.

Many tantalum-containing ores such as tantalite, vodginite columbite, and microlite contain significant amounts of niobium (Nb).
