Descrizione

Descrizione generale

Ta₂O₅ (tantalum pentoxide) is a transition-metal oxide with a high refractive index (n=2.02–2.16), high dielectric constant, wide bandgap (4.0–4.5 eV), and wide transmission spectrum. It is a non-silicon dielectric material used in microelectronic devices and the ideal capacitive material for next-generation multi-chip modules. Due to its high acidity, it can serve as a catalyst for the oxidation of alkanes and pollution reduction. In addition, it is successfully used for the anode oxidization of electrodes in lithium batteries.

Applicazioni

• Double-layered nanoparticle stacks for spectro-electrochemical applications.: This study discusses the development of double-layered nanoparticle stacks incorporating Tantalum(V) oxide, which have significant potential in spectro-electrochemical applications due to their high refractive index and dielectric properties (Frank et al., 2012).
