Tantalum pentoxide also known as tantalum(V) oxide is the inorganic compound with the formula Ta2O5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta2O5 is an inert material with has a high refractive index and low absorption (i.e. colourless) which makes it useful for coatings. It is also extensively used in the production of capacitors due to its high dielectric constant.
