Tantalum Pentoxide Micron Powder

Tantalum Pentoxide is a chemical compound with the symbol Ta2O5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Its melting point is nearly 1872℃ and has a density of 8.2 g/cm3. Like many metal oxides Ta2O5 is an insulator and its band gap has variously been reported as being between 3.8 and 5.3 eV, depending on the method of manufacture. Owing to its high band gap and dielectric constant, tantalum pentoxide micron powder 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. Due to its high refractive index, Ta2O5 has been utilized in the fabrication of the glass of photographic lenses.
