Application

1. Electronics industry: Niobium pentoxide plays an important role in the electronics industry, mainly used to manufacture anode material nickel niobate, as well as high-frequency and low-frequency capacitors, piezoelectric ceramic components and other electronic components.

2. In the field of optics, niobium pentoxide is mainly used in the manufacturing of special optical glass and optical lenses, which can improve the refractive index of glass and reduce dispersion. It is widely used in industries such as liquid crystal displays and photovoltaic power generation.

3. Catalyst: Niobium pentoxide can be used as a catalyst or catalyst carrier to participate in various chemical reactions, such as playing a catalytic role in organic synthesis reactions.

4. Ceramic materials: In the field of ceramics, niobium pentoxide is used to prepare potassium sodium niobate ceramics (KNN), which have the characteristics of dense texture, low mechanical quality factor, and high Curie temperature. As a piezoelectric ceramic, it can be used to manufacture various electronic components without lead and has outstanding environmental protection. In the future, it is expected to replace traditional lead zirconate titanate ceramics (PZT).

5. Energy storage materials: Research has found that niobium pentoxide can be used as an electrode material for batteries. While providing good storage capacity, it can accelerate the charging of lithium-ion batteries and is less prone to crystallization, making it safer and more durable than graphite.

6. Metallurgy and alloys: Niobium pentoxide is used as a steel modification additive in the metallurgical industry to improve the yield strength of steel.
