Abstract (english): A High-Throughput Experimental (HTE) approach starting from dry, fine-grained
powders was used to synthesize bulk samples in the system (KxNa1-x)1-yLiy(Nb1-zTaz)O3, a doped variant of the piezoelectric (K0.5Na0.5)NbO3 (KNN). Starting from the system (K0.5Na0.5)1-yLiy(Nb1-zTaz)O3 known from the works of Saito et al. an effort was made toestablish a higher-order phase diagram. Special emphasis was put on expanding the known morphotropic phase boundary that constitutes a region of special interest for electroceramic materials as it features maximum piezoelectric properties. Analyses were performed using a HTE-compatible technique, namely automated powder X-ray diffraction (XRD).
