Product name:Tantalum oxide CAS:********0 Molecular formula:Ta2O5 Molecular weight:**1.**3 Product Description:Tantalum pentoxide is Ta2O5, also known as tantalum(V) oxide. Both orthorhombic and hexagonal phases are known. Ta2O5 is a high refractive index, low absorption material useful for coatings in the near-UV to IR spectra regions; it decomposes only at temperatures >***0 °C. Use:Ta2O5 is used to make capacitors in automotive electronics, cell phones, and pagers, electronic circuitry; thin-film components; and high-speed tools. In the ***0s, there was a very strong interest to do research on tantalum oxide as a high-k dielectric for DRAM capacitor applications. For example, Elpida Memory (a Japanese company making DRAM) has put in a strong effort to improve ultrathin tantalum oxide films for DRAM applications. Subsequently in the ***0s, this strong interest has dropped very significantly. There is still some interest to use it in MIM capacitors for RF CMOS integrated circuits. Due to its high index of refraction, Ta2O5 has been utilized in the fabrication of the glass of many photographic lenses.
