Multi-phase structure and optimal properties of (Ba1-xCax)(Ti0.93Zr0.01Sn0.06)O3 ceramics in the MPB range
(0.93 − x)BT − 0.01BZ − 0.06BS − xCT or (Ba1-xCax)(Ti0.93Zr0.01Sn0.06)O3 (abbreviated as BCZTS) ceramics were produced using the standard solid-state reaction for 0.045 ≤ x ≤ 0.07. For the samples, it was found that orthorhombic (Amm2), rhombohedral (R3m) and tetragonal (P4mm) structures coexisted in two phases as well as three phases with distinct phase fractions. The largest size of crystalline grains was achieved after doping with 0.055 mol% and 0.065 mol% Ca. The optimal properties (Pmax = 12.05 μC/cm2, Pr = 5.61 μC/cm2, Ec = 230 V/mm, d*33 = 404 pm/V, Qc = 6.44 µC/cm2, Tc = 102 °C) were obtained for x = 0.07 where it has been found that orthorhombic, rhombohedral, and tetragonal phases all occurred at the same time. For compositions in the MPB range, the energy storage characteristics indicate high energy storage efficiency for low value of Ca doping. Given all the developments, it is obvious that Ca, Zr and Sn-doped BCZTS ceramics would be a good choice for lead-free electronics.
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.
