Stoichiometric Pb(Fe1/2Nb1/2)O3 perovskite ceramics produced by reaction-sintering process

Synthesis of Pb(Ni1/3Nb2/3)0.72Ti0.28O3 perovskite ceramics by a reaction-sintering process

“…7 Variation of density with sintering temperature for PNNT ceramics in PbO compensated atmosphere PFN, PMN-PFN and PMN-PZN perovskite ceramics by a reaction-sintering process. Pure perovskite phase could be obtained in these materials without any PbO compensation (mixed into the pellets or added beside the pellets) [13][14][18][19]. The results in Fig.…”

“…In this mechanical technique, the powder of reactants are homogenized and activated in a high-energy vibromill. Liou and co-workers further developed a reaction-sintering process to produce pyrochlore-free PMN and Pb(Fe 1/2 Nb 1/2 )O 3 (PFN) ceramics [13,14]. The mixture of PbO, Mg(NO 3 ) 2 (or Fe(NO 3 ) 3 ) and Nb 2 O 5 was pressed and sintered directly into PMN and PFN ceramics without any calcination stage involved.…”

Non-calcining process for CuAlO2 and CuAl0.9Ca0.1O2 ceramics

“…In previous studies, our group had prepared Pb(Mg 1/3 Nb 2/3 )O 3 (PMN) and Pb(Fe 1/2 Nb 1/2 )O 3 (PFN) ceramics via a simple and effective reaction-sintering process [18,19]. PbO and Nb 2 O 5 that were mixed with Mg(NO 3 ) 2 or Fe(NO 3 ) 3 were then pressed and sintered directly into PMN and PFN ceramics with the calcination step bypassed.…”

Effect of dopants on synthesis of BaTi4O9 and Ba2Ti9O20 ceramics prepared by reaction-sintering process

“…11 Liou et al reported a simple and effective reactionsintering process in preparing Pb(Mg 1/3 Nb 2/3 )O 3 (PMN), Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) and Pb(Fe 0.5 Nb 0.5 )O 3 (PFN) ceramics. [12][13][14][15][16][17] These are the first successful synthesis of perovskite relaxor ferroelectric ceramics without any calcination involved. PMN ceramics with a density of 8.09 g/cm 3 (99.5% of the theoretical value) and high dielectric constant 19,900 (1 kHz) were obtained.…”
