niobium oxide powder
Product Description
Niobium pentoxide powder is an important compound material, its main chemical composition is niobium pentoxide (Nb2O5). The physical properties of niobium pentoxide powder include its crystal structure, density, melting point and boiling point. Niobium pentoxide powder also has good thermal stability, enabling it to remain stable in high temperature environments. The chemical properties of niobium pentoxide powder include its acid-base, oxidation reduction and so on. Niobium pentoxide powder is insoluble in water, but soluble in acid and base, showing a certain acid-alkali. Niobium pentoxide also has oxidative reducibility and can be oxidized or reduced at different temperatures and atmospheres. Niobium pentoxide powder has a wide range of applications in many fields. In the electronics industry, niobium pentoxide powder can be used to manufacture electronic components, optical devices and high temperature superconducting materials. In the field of coatings, niobium pentoxide powder can be used to prepare high-grade coatings and pigments. In addition, niobium pentoxide powder can also be used in the manufacture of optical glass, ceramics and catalysts.
