Densification and properties of barium zirconate ceramics by addition of P2O5

Effect of phosphorus additions on the sintering and transport properties of proton conducting BaZr0.85Y0.15O3−δ

“…Such phosphorous additions have also been shown to decrease the sintering temperature of BaTiO 3 through the formation of P-and Ba-containing phases that improve porosity coalescence and removal [23,24]. Analogously, the addition of phosphorous has recently been shown to slightly lower the sintering temperature required for attaining high density in barium zirconate ceramics while also improving mechanical properties [25]. Furthermore, the stability of a P-based sintering additive towards reduction is expected to be higher than that of common transition metal oxide sintering additives, such as NiO or CoO, thus avoiding the subsequent appearance of electronic conductivity in the reducing conditions of operation [11][12][13].…”

Examination of the co-sintering process of thin 8YSZ films obtained by dip-coating on in-house produced NiO–YSZ

“…In a study by Gao and Guo, doping of barium zirconate with P 2 O 5 affected the sintering behaviour of the ceramic. 33 The microstructure became denser by the addition of P 2 O 5 . Residues of P 2 O 5 were also found to produce reaction products with the ceramic indicating that a liquid-phase sintering mechanism was present.…”

Dip-coating of 8YSZ nanopowder for SOFC applications

“…In the literature, phosphorus has been known to affect the sintering properties of the material by liquid-phase sintering [39]. Also, the electrochemical properties of SOFC components have been reported to be affected by introducing phosphorus during cell operation [40,41].…”
