Tantalum oxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta 2 O 5 . It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Tantalum Oxide (Ta2O5) Sputtering Targets (Size:2'' ,Thickness:0.125'' , Purity: 99.99%) is an inert material with a high refractive index and low absorption which makes it useful for coatings. It is also extensively used in the production of capacitors, due to its high dielectric constant. Tantalum oxide films are of interest for applications in high temperature resistance, anti-reflection coatings for solar cells, optical waveguide, oxygen sensors, and capacitor dielectric materials. In recent years they have received increasing attention as an alternative dielectric to replace thin SiO, films for storage capacitors in very large-scale-integrated memory cells and as gate insulators in metal-oxide-semiconductor devices. Tantalum oxide films can be formed...
