Advanced Sintering Techniques in Design of Planar IT SOFC and Supported Oxygen Separation Membranes

Rational synthesis of 10GDC electrolyte through a microwave irradiation GNP facile route for SOFC applications

“…The FE-SEM images reveal the formation of diffused fine crystalline particle growth during the microwave sintering of 10GDC even at 800 °C compared to the conventionally sintered YSZ at temperature ≥1400 °C reported earlier. 23,29 Fig. 2(a–d) suggests that the microwave heating offers an ultra-fast method for ceramic preparation with an ultra-large heating rate compared to the conventional sintering methodologies.…”

“… 27 The crystallite size of the 10GDC sample is found to be in the range of 15–28 nm, while the sintered density is found to be 6.98 g cm −3 , showing a close agreement with the standard density of 10GDC (7.22 g cm −3 ). 23 The growth in crystallite size is observed due to higher densification with increase in temperature in the microwave irradiation process. The XRD phases reveal the lattice group Fm 3̄ m with respect to the cubic fluorite structure corresponding to the lattice parameter, a = b = c = 0.54 nm.…”

Kinetic assessment of dry reforming of methane on Pt + Ni containing composite of fluorite-like structure

“…To suppress coking that leads to the deterioration of the anode performance at lower temperature, a promising approach is to promote traditional Ni/YSZ cermets by complex oxides with a high oxygen mobility along with small amounts of precious metals (Pt, Pd, Ru). The catalytic properties are strongly affected by the interactions between composite nanoparticles and support [13][14][15][16][17][18][19][20]. Precious metal atoms incorporated into the surface layer of Ni particles provide sites for activating fuel molecules while decreasing the carbon nucleation probability, whereas the complex oxides of the support will transfer oxygen species to active sites, hence, preventing the deactivation by coking [16][17][18][19][20].…”

Synthesis and Oxygen Mobility of Bismuth Cerates and Titanates with Pyrochlore Structure

“…With traditional thermal sintering in a furnace, long-term processing, and high temperatures are required to obtain ceramics with desired properties, such as gas tightness, homogeneous phase composition, etc. To solve this problem, radiation-thermal sintering (e-beam processing) is proposed [ 37 , 38 , 39 , 40 , 41 ]. Using the main advantages of radiation-thermal reactions—lowering the treatment temperature and a high reaction rate—will reduce the processing time while also significantly reducing internal thermal stresses.…”

“…structures or their nanocomposites, such as LFN-GDC, LFC-GDC, La 0.3 Bi 0.7 MnO x –Bi 1.5 Y 0.3 Sm 0.2 O 3 , etc.) using unique equipment of the Budker Institute of Nuclear Physics [ 37 , 38 , 39 , 40 , 41 ]. Disordering of nanodomains by electron beams leads to their easy sintering at moderate temperatures without increasing their sizes.…”
