Bi(1−x)GdxFeO3 (BGFO, x=0.05–0.3) crystallites were synthesized by the microwave hydrothermal method. Then, the powders were sintered into shaped BGFO ceramics. The results showed that Gd3+ could dramatically affect the structural, ferroelectric and magnetic behavior of BiFeO3 ceramics. X-ray diffraction results indicated that pure BGFO ceramics could be obtained. The morphologies of the BGFO are...
Monophasic rhombohedral structure of high pure BiFeO3 was successfully synthesized by microwave hydrothermal method. Then the obtained powders are processed under different microwave calcination temperatures. The results show that the microwave calcination temperature can dramatically affect the structural, microstructural, dielectric, ferroelectric and magnetic behavior of BiFeO3 ceramics. The morphologies...
As one of the most important multiferroic composite systems, the 0.9BaTiO3-0.1BaFe12O19 (0.9BT-0.1BFO) composite was prepared by conventional sintering (CS) and microwave sintering (MS) techniques. High density ceramics were obtained by MS method in 70 min of cycle time, whereas it took 748 min by CS method. The phase composition and diphase microstructure of the composite samples were examined by...
