NIOBIUM PENTOXIDE (Nb2O5) -  Optimum optical components

Niobium pentoxide (Nb2O5) increases both the refractive index of optical glasses and the capacity of multi-layered ceramic capacitors (MLCCs). In contrast to lead oxide, niobium pentoxide poses no health risks.

When niobium pentoxide is added to the glass during the production of optical lenses, the lenses are lighter, thinner and demonstrate greater resilience.

Niobium Pentoxide
In addition, niobium pentoxide in interchangeable lenses makes them lighter while enabling better performance in digital cameras and mirrorless system cameras. Adding niobium pentoxide to spherical lenses allows the number of lenses in optical elements to be reduced, which makes the components lighter and smaller. When niobium pentoxide is used as a dopant in the production of multi-layered ceramic capacitors (MLCCs), the Curie temperature of the barium titanate substrate can be increased, this enables the best possible temperature stability to optimize capacity.

Top crystal properties and profitable production

As a substrate for surface acoustic wave filters, also known as SAW filters, lithium niobates are found in mobile end devices such as smartphones, tablet PCs, ultrabooks, GPS applications and smart meter. These niobium containing radio frequency filters, ensure precise frequency control, optimized selectivity and reduced distortion.

As a dopant, niobium pentoxide improves the piezoelectric performance of lead zirconate titanate (PZT). Thanks to electronically controlled piezo actors, high-pressure diesel injection enables greater efficiency in the automobile industry due to shorter reaction times. H.C. Starck Tantalum and Niobium provides a wide variety compounds (including niobates and oxalates) that are needed as additives for lead zirconate titanate (PZT), the primary substance now in use.

In all of these applications, the high degree of chemical purity of niobium pentoxide guarantees the best performance. In addition to the regular particle morphology, H.C. Starck Tantalum and Niobium also supplies spherical niobium pentoxides. Due to their good flow characteristics and high settled density, they can be used in other applications as spray powders.
