Tantalum (V) Oxide Ta2O5(Tantalum Pentoxide) 1314-61-0

Tantalum (V) oxide (Ta2O5 or Tantalum Pentoxide) is a white, stable solid compound. The powder is produced by precipitating a tantalum containing acid solution, filtering the precipitate, and calcining the filter cake. It is often milled to the desirable particle size to meet various application requirements.

What is Tantalum Oxides and Tantalum Pentoxides used for?

Tantalum Oxides are used as a base ingredient for lithium tantalate substrates required for the surface acoustic wave (SAW) filters used in:

• mobile phones,• as a precursor for the carbide,• as an additive to increase the refractive index of optical glass,• as a catalyst, etc.,while niobium oxide is used in electric ceramics, as a catalyst, and as an additive to glass, etc.

As a high reflective index and low light absorption material, Ta2O5 has been used in optical glass, fiber, and other instruments.

Tantalum pentoxide (Ta2O5) is used in the production of lithium tantalate single crystals. These SAW filters made of lithium tantalate are used in mobile end devices such as smartphones, tablet PCs, ultrabooks, GPS applications and smart meters.
