High energy storage, structure evolution and dielectric properties of complex perovskite solid solution (1-x) NaNbO3-xBi (Zn2/3Nb1/3) O3
NaNbO3-based lead-free ceramics show great potential in energy storage and piezoelectric applications due to the antiferroelectric and ferroelectric features. However, pure NaNbO3 usually shows lossy hysteresis loops because of the metastable antiferroelectric phase at room temperature. In this work, Bi(Zn2/3Nb1/3)O3 was introduced into NaNbO3 to modulate the phase structure, dielectric, and energy storage properties. The addition of Bi(Zn2/3Nb1/3)O3 changed the phase structure from orthorhombic to pseudo-cubic, decreased the grain size from ~ 20 μm to ~ 1 μm, shifted the temperature of dielectric peak from 360℃ to room temperature, and led to much-reduced polarization hysteresis and improved breakdown strength. With the addition of 9 mol% Bi(Zn2/3Nb1/3)O3, the maximum recoverable energy density of 3.3 J/cm3 was achieved under 33.5 kV/mm. These results provide a feasible route to design and fabricate new NaNbO3-based energy storage ceramics.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
