Applications

Ta₂O₅ (Tantalum (V) Oxide or Tantalum Pentoxide) is used in ceramics, glass, and capacitor materials. Due to its dielectric constant and high band gap it has been used extensively in electronics. Other applications include optics and glass due to its high refractive index. Ta₂O₅ is also a material used to produce Ta-doped LLZO garnet solid state electrolyte materials, which can be ordered from MSE Supplies.
