Tantalum(V) Oxide (Ta₂O₅)

Tantalum(V) Oxide (Ta₂O₅), Tantalum Pentoxide, is a white solid that is insoluble in all solvents. It is an inert material with a high refractive index and low absorption, which makes it useful for coatings. It has a high dielectric constant and a high bandgap. It also has high biocompatibility and resistivity.

Powder Size as small as 0.65 microns

Purity: 99.0%-99.997%
Typical Applications

Tantalum (V) Oxide is used in the production of capacitors, resistive switching memories, high-frequency CMOS integrated circuits, DRAM (Dynamic Random Access Memory) capacitor applications, and in the fabrication of optics and glasses and coatings. It has been shown to improve corrosion resistance and cytocompatibility of titanium substrates and has attracted many biomedical applications.

Packaging Options
