Quiet & efficient driving experience with piezo ceramics

Niobates are anorganic compounds that contain niobium and oxygen. These materials are characterized by good piezoelectric properties. To meet the needs of numerous applications, H.C. Starck Tantalum and Niobium provides a wide variety of niobium compounds. Our niobate product group includes magnesium niobate and potassium niobate, among others.

Niobates are used as a dopant for PZT ceramics (lead zirconate titanate) in the production of piezo actors, for example. 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 the main component in dielectric lead zirconate titanate.
