Low Temperature Fabrication of Lead-Free KNN-BNT Ceramics via the Combustion Technique

Fulleropyrrolidine-functionalized ceria nanoparticles as a tethered dual nanosystem with improved antioxidant properties

“…The blue line shows the multistage thermal decomposition of nanoceria; the rst step (198 C) corresponds to the urea conversion into liquid ammonia isocyanic acid (HNCO) while the second (303 C) is related to the rapid vaporization of ammonia as a consequence of HNCO hydrolysis. 49 In the range between 370 and 600 C, the mass loss is attributed to the conversion of residual Ce(OH) 3 , which is on the nanoceria surface, into CeO 2 . 50 The thermogravimetric curve of Si-Fulp (Fig.…”

Phase formation and electrical properties of SBNLT ceramics prepared via combustion technique

“…[18] showed a higher ferroelectric property ( P max ∼20 µC/cm 2 ) compared to the solid state reaction method ( P max ∼8 µC/cm 2 ) [19]. Likewise, Krailas Mathrmool et al [20] reported a decrease in the calcination temperature and soaking time of 0.97(K 0.5 Na 0.5 NbO 3 )-0.03(Bi 0.5 Na 0.5 TiO 3 ) ceramics from 900°C for 5 h to 700°C for 3 h, as compared to the conventional mixed oxide route [21]. It was found that the phase structure, microstructure, dielectric, ferroelectric, and energy storage properties of Sr 0.3 (Bi 0.7 Na 0.67 Li 0.03 ) 0.5 TiO 3 (SBNLT) ceramics prepared by the solid-state combustion technique are still unknown.…”
