Microstructure and dielectric properties of strontium barium niobate ceramics synthesized by partial coprecipitation

Effect of CASP glass doping on sintering and dielectric properties of SBN ceramics

“…The observed dielectric constants of the CASP glass-doped SBN50 ceramics are very larger than the reported values (ε max ≈ 1611) for SBN50 synthesized by partial co-precipitation and combustion synthesis [15,13].…”

A novel sol–gel route to synthesize (Sr0.5Ba0.5)Nb2O6 ceramics with enhanced electrocaloric effect

“…To lower the synthesis temperature and decrease the particle size, scholars proposed the use of wet chemical methods. Co-precipitation reaction 22 and the sol-gel route 23,24 have been employed previously. In these methods, expensive and unstable organic metallic compounds are used, and dry argon gas is flushed into the reaction container to protect the solution from water.…”

Elastic and anelastic relaxations accompanying relaxor ferroelectric behaviour of Ba6GaNb9O30 tetragonal tungsten bronze from resonant ultrasound spectroscopy

“…Early attempts focused on tungsten bronzes of nominal composition A 6 B 10 O 30 (mainly compositions where the C-sites are vacant). A particular interest was developed regarding the Nb-based TTBs [15][16][17] due to their enhanced ferroelectric properties over other analogues such as Ta [18,19]. In the search for novel multiferroic and magnetoelectric materials, the effect of the A-site size in a family of unfilled ferroelectric TTBs Ba 4 RE 0.67 Nb 10 O 30 (RE = La, Nd, Sm, Gd, Dy, Y) [6] and of the A-site strain on dipole stability in fully filled TTBs family A 6 GaNb 9 O 30 (A = Ba, Sr, Ca) [7,20] was studied.…”
