Abstract (en)
[origin: WO2022175030A1] The present invention relates to a niobate powder of the general composition Li(Na/K)NbO3 for piezoelectric applications, the niobate powder having a carbon content of 10 to ppm/(m²/g) relative to its BET surface area. The invention further relates to a method for producing the niobate powder and to its use in the production of piezoelectric materials.
