Phase transitions in lead free piezoelectric materials
(K0,5Na0,5)NbO3 doped with 1 mol% SmBO3 (where B= Al, Co, Cr, Fe, Mn) ceramics were obtained through solid state method in air. The refinement of the unit cell reveals a shift from orthorhombic to tetragonal crystalline structure at room temperature, for KNN-SmMnO3, KNN-SmFeO3 and KNN-SmCrO3. The va...

| Tartalmi kivonat: | (K0,5Na0,5)NbO3 doped with 1 mol% SmBO3 (where B= Al, Co, Cr, Fe, Mn) ceramics were obtained through solid state method in air. The refinement of the unit cell reveals a shift from orthorhombic to tetragonal crystalline structure at room temperature, for KNN-SmMnO3, KNN-SmFeO3 and KNN-SmCrO3. The variation of the dielectric constant at different frequencies shows an increase of almost one order of magnitude for KNN-SmCoO3 and KNNSmMnO3, compared to the reference KNN. |
