چکیده
Relaxed ferroelectric ceramics with good energy storage stability, high density and efficiency, charge/discharge rates have shown great potential for commercial applications. In this paper, 0.85[0.9BaTiO3 −0.1Bi(Ni0.5Zr0.5)O3]−0.15(Bi0.5Na0.5)0.7Sr0.3TiO3 ceramic was prepared via a solid – phase reaction method by doping (Bi0.5Na0.5)0.7Sr0.3TiO3 into 0.9BaTiO3 > −0.1Bi(Ni0.5Zr0.5)O3; it exhibited excellent performance values: Wrec = 2.87 J/cm3 η 88.10%. Charging discharging tests were conducted to evaluate the feasibility of practical applications in devices; displayed an ultrafast discharge rate 1.16 μs. addition, developed has frequency stability (1–120 Hz) temperature (40–160°C). This indicates that is suitable candidate pulse power devices.

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

xBaZrO3-(1!x)BaTiO3 solid solutions (x 1⁄4 0, 0.04, 0.06, 0.08, 0.12, and 0.18) synthesized via conventional solid state reaction method exhibit piezoelectric coefficients comparable to those of “hard” PZT-8, PZT-4, and even “soft” PZT-5A. Doping also improves the poling efficiency of xBaZrO3-(1!x)BaTiO3 ceramics. Study of temperature dependence of the dielectric and piezoelectric properties re...
