Dense KNN Polycrystals Doped by Er<sub>2</sub>O<sub>3</sub> Obtained by Hot Pressing with Hexagonal Boron Nitride Protective Layer

Analysis of dense Potassium Sodium Niobate (KNN) ceramic obtained by hot pressing (HP) method at 1100 °C are presented in this paper. The synthesis of KNN-based piezoelectrics meets the following challenges—low density of material, uncontrolled K/Na ratio, multiphase composition and formation of dif...
