Effect of the fuel type on the synthesis of yttria stabilized zirconia by combustion method

The Effect of Fuel Types on Porous Alumina Produced via Soft Combustion Reaction for Implant Applications

“…This result proved that a higher surface area can be obtained using AG. The pattern observed in glycine samples is concurrent with previous study (Ref 12) where they acquire more loose and porous structure that can be attributed to the evolution of large amount of gases during combustion reaction. Even though AU has the highest temperature during the combustion process, the characteristic of its indecent flame growing after auto-ignition may cause partial sintering resulting in pore size shrink.…”

Development of Ni-doped Yttria stabilized Zirconia composite for SOFC applications as Anodic material

“…These are (i) sonochemical preparation, (ii) co-precipitation, (iii) electro-less co-deposition, (iv) hydro-thermal synthesis, (v) spray pyrolysis , (vi) tape casting, (vi) mechanical mixing or ball milling of individual powders followed by compaction and sintering, and (vii) combustion synthesis etc [3,13]. Since properties of Ni/YSZ anodes are mostly dependent on the particle size and the microstructure of the cermets, among various methods stated above, combustion synthesis is a simple and cost effective to produce very fine, homogeneous with high purity, a narrow particle size distribution with high specific surface area and highly crystalline powders [3,13,14] without any intermediate step. It consists of a self-propagating high temperature synthesis (SHS), discovered by Merzhanov and co-workers, which involves a wide variety of chemical routes and products [14].…”

In combustion synthesis, nano-powders or loose agglomerates of nano-crystallites are produced in reaching high temperature in a short reaction time by self-generated heat of reaction [2].…”

“…In combustion synthesis, nano-powders or loose agglomerates of nano-crystallites are produced in reaching high temperature in a short reaction time by self-generated heat of reaction [2]. Different fuels such as sucrose, glycine, citric acid, carbohydrazide, urea etc., have been used in this method as fuel [1,3,14].…”

Scalable synthetic method for SOFC compounds

“…is greater than that of urea (−2.98 kcal g − 1 ) or citric acid (−2.76 kcal g − 1 ), being more stronger complexing agent and forming stable gels in nitrate solution [9][10][11][12]. The advantages of the glycine nitrate combustion process are relatively low cost, fast heating rates, short reaction times, high composition homogeneity and high energy efficiency [13].…”
