Utilisation of methylcellulose as a shaping agent in the fabrication of Ba0.95Ca0.05Ce0.9Y0.1O3 proton-conducting ceramic membranes via the gelcasting method

Abstract: The gelcasting method was used to form gastight Ba 0.95 Ca 0.05 Ce 0.9 Y 0.1 O 3 samples proposed for use as proton-conducting electrolytes in solid oxide fuel cells. Methylcellulose was used as an environmentally friendly shaping agent for Ba 0.95-Ca 0.05 Ce 0.9 Y 0.1 O 3 powder in an ethanol solution. Samples of Ba 0.95 Ca 0.05 Ce 0.9 Y 0.1 O 3 were also prepared from the same powder via traditional isostatic pressing, as a reference for cast samples, and sintered in the same conditions.

“…The pores size distributions decreased as ROM (6:1 to 14:1) and sintering temperatures (650°C to 1050°C) increases. Authors [26][27][28] stated, these parameters can be attributed to more consolidation of the membrane powders as the temperature and ROM varied. Thus, affect the pores size distributions.…”

“…A small portion of mixed reagents prepared for the SBCY-series powders was calcined within a temperature range of 850−1150 • C for 2 h. The monophase orthorhombic phase for all investigated compositions of the SBCY series was found at a temperature of 1150 • C. Subsequently, a 200 g portion of powder was synthesized at 1200 • C for 2 h. The SBCY powders were additionally ground in dry ethanol. The total milling time for monophase SBCY powder samples was 6 h. The details of the homogenisation procedure and milling conditions for the monophase samples was described in the previous paper [30]. The BSCY disc samples were formed via the isostatic pressing method, using a National Forge isostatic cold press, EPSI Engineered Pressure Systems International N.V. (Temse, Belgium).…”
