文摘

Fabricating new 0.96(K0.5Na0.5)(Nb0.96Sb0.04)O3-0.04ZnZrO3 ceramics by normal sintering. Investigating the effects of (Bi0.5K0.5) contents on their phase structure and electrical properties. Constructing the rhombohedral-tetragonal phase boundary. Obtaining a high piezoelectricity of d33 = 442 pC/N and kp = 50%.
