Gel-combustion, characterization and processing of porous Ni–YSZ cermet for anodes of solid oxide fuel cells (SOFCs)

Nanocrystalline La0.84Sr0.16MnO3and NiO-YSZ by Combustion of Metal Nitrate-Citric Acid/Glycine Gel – Phase Evolution and Powder Characteristics

“…17 It was observed that green density of these NiO-YSZ compacts increased continuously as the calcination temperature of the powder increased; it was expected that the sintered density would also increase. The NiO-YSZ compact made from asprepared powder exhibited 62% TD with 38% open porosity while a maximum TD of 69% with 31% OP was obtained for the sintered compacts fabricated from 1350 o C calcined powder.…”

Influence of sintering temperature and aging on properties of cermet Ni/8YSZ materials obtained by citric method

“…Nowadays, the methods of wet chemical synthesis are often used in order to obtain homogenous and nanosize particles. Some original methods of synthesis described in literature are co-precipitation by NaOH method [4], nitrates combustion [5], combustion citrate-nitrate method [6], classical Pechini method [7], combustion of nitrate-glycine gel [8], sol-gel method with sucrose and pectin addition [9], complex-gel conversion process by EDTA [10], selfassembled NiO-YSZ directionally solidified eutectics method [11] and precipitation of NiO or Ni precursors on YSZ [12,13]. The characteristic feature of these methods is that synthesized materials have uniform nanostructure and high level porosity without a necessity of using a pore former.…”

Mechanical and Tribological Properties of Al2O3-TiC Composite Fabricated by Spark Plasma Sintering Process with Metallic (Ni, Nb) Binders

“…Thus, researchers have been attempting to address these issues by replacing Co with other transition elements, such as Ni, Mo, and Ni-Mo. Ni is one of the prominent candidates as a binder, which can be widely utilized in various types of cermets [18,19]. The addition of transition and relatively soft material like Ni may have a significant influence in reducing the crack growth during the sintering process, due to its excellent oxidation resistance [20,21].…”
