“…The weight loss of the sample occurs at 750–1000 °C because of the B 2 O 3 volatilization that occurs under high-temperature sintering. When the Ba: B molar ratio was 1:2, Ba(BO 2 ) 2 formed at a temperature of 1060 °C . The resulting liquid phase promotes particle rearrangement, low diffusion mass transfer resistance, and fast flow mass transfer in the liquid phase, which promotes BZCY densification.…”

“…The BaO-B 2 O 3 multiple sintering aids successfully decreased the sintering temperature of BaZr 0.85 Y 0.15 O 3−δ below 1400 °C. The presence of the liquid phase promoted bulk diffusion, and a dense structure with a relative density of 94% was obtained . Babar et al sintered the BaCe 0.7 Zr 0.1 Y 0.2 O 3−δ electrolyte at 1150 °C using CuO-Bi 2 O 3 as a dual sintering additive .…”

Influence of Triple Sintering Additives (BaO-CuO-B₂O₃) on the Sintering Behavior and Conductivity of the Proton-Conducting BaZr_0.1Ce_0.7Y_0.2O_3−δ Electrolyte Sintered at 1150 °C

The effects of multiple sintering additives BaO-CuO-B 2 O 3 on the sintering behavior, microstructure, and electrochemical performance of BaZr 0.1 Ce 0.7 Y 0.2 O 3−δ (BZCY) as an electrolyte were investigated for intermediate temperature solid oxide fuel cell application. BZCY was prepared by adding 0, 1, 2, and 3 mol % sintering additives through the freeze-drying method. Microstructure analysis and shrinkage measurement reveal that BZCY with 3 mol % sintering additive effectively reduces the sintering temperature to 1150 °C. BZCY pellets with 3 mol % sintering additives sintered at 1150 °C for 8 h increased the linear shrinkage from 2.6 to 17.0%. Thermochemical analysis reveals that the low melting temperature eutectic phase formation resulted in liquid-phase sintering, which supports the rearrangement and densification of BZCY particles. BZCY with 3 mol % sintering additives presented a proton conductivity of 0.016 S cm −1 and good durability at 600 °C with a low activation energy of 0.44 eV and low grain boundary resistance.

“…The influence of sintering aids on the electrical conductivity is very often discussed in the literature. Thus, Jiao et al [29] suggested that the sintering aids segregate at grain boundaries and block proton conduction, revealing a negative effect on the conductivity. Babilo and Haile [10], Reddy and Bauri [15] and Baral [30] explained a reduction in conductivity by attributing it to the defect interactions and associations and the proton-dopant trapping effect.…”

Precursor powders for BaCe0.2Zr0.7Y0.1O3-?(BCZY27) ceramics were synthesized by a modified Pechinimethod and calcined at 900?C for 12 h. The calcined BCZY27 powders were milled in eccentric and in high energy mill with the addition of 2 and 4mol% ZnO as sintering aid. The effects of milling and sintering aids on the sinterability and electrical conductivity were studied. The linear shrinkage in thermomechanical analyses started at 1050?C for the BCZY27 with 4mol% ZnO processed in eccentric mill. Theoretical density above of 90%TD was obtained for the BCZY27 milled with 4mol% ZnO and sintered at 1400?C for 4h. X-ray diffraction analysis of the BCZY27 ceramics sintered at 1400?C confirmed the presence of BaCe0.2Zr0.7Y0.1O3-? and Y0.4Ce0.6O1.8 phases. The incorporation of Zn into perovskite lattice leads to the secondary phase formation. SEM and EDS analyses confirmed the presence of Y0.4Ce0.6O1.8 phase. The sintering was assisted by BaO-ZnO eutectic, which was reflected by the increase of activation energy values for grain boundary conduction. The milling processing did not affect the conductivity properties. The obtained BCZY27 dense sample has conductivity of 7.60 ? 10?3 S/cm at 500?C.
