Tantalum Oxide, 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 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 highdielectric constant.

Appearance:
white crystal powder

Application:
  In electronics

Owing to its high band gap and dielectric constant, Ta2O5 Tantalum Oxide has found a variety of uses in electronics, particularly in tantalum capacitors. These are used in automotive electronics, cell phones, and pagers, electronic circuitry; thin-film components; and high-speed tools. In the 1990s, interest grew in the use of tantalum oxide as a high-k dielectric for DRAM capacitor applications., It is used in on-chip metal-insulator-metal capacitors for high frequency CMOS integrated circuits. Tantalum oxide may have applications as the charge trapping layer for Non-volatile memories., There are applications of tantalum oxide in resistive switching memories.

Other uses
Due to its high refractive index, Tantalum Oxide has been utilized in the fabrication of the glass of photographic lenses.
