Niobates

Materials for Piezoceramics

Niobates are inorganic compounds which consist of niobium, another metallic element and oxygen. These materials can be used for production of electroceramic components such as piezoceramics. By using highly reactive niobium precursors for the production of our niobates, we are able to supply niobates with high homogeneity and a wide range of particle sizes. Our niobates product portfolio includes:

  • Magnesium niobate (MgNb2O6)
  • Potassium niobate (KNbO3)
  • Other niobates/tantalates are available on request

Our potassium niobate as well as our niobium pentoxide ceramic grade are used as a dopant for PZT (Lead Zirconate Titanate) in the production of piezo actors and sensors. Electronically controlled piezo actors are used in high-pressure diesel injection systems to ensure considerably more efficient and trouble-free handling along with lower emission values.

Magnesium niobate is a main component in PMN-PT (Lead Magnesium Niobate – Lead Titanate) with extremely high piezoelectric constants. It is applied in ceramic as well as in single crystal piezoelements e.g. for medical applications.

Moreover, we are developing the materials for LFPZ (Lead Free Piezoceramics) based on Potassium sodium niobate (KNN) compounds. Follow the link for more Information.
