3N5 (99.95%) Niobium Oxide (Nb2O5) Pieces (3-12mm) Evaporation Materials

Niobium Oxide (Nb2O5) is widely used in catalysis, electrochromic and photoelectrochemical devices. It has been used as a water-tolerant solid acid catalyst for many reactions such as alkylation, esterification, hydrolysis, dehydration and hydration. It is also a trending optical thin film coating material due to its high refractive index over the full visible range. 

The dimensions and purities can be customized upon request. Please contact us for customization or bulk orders.
