Salt-assisted combustion synthesis of highly dispersed superparamagnetic CoFe2O4 nanoparticles

Nanomaterials via solution combustion synthesis: a step nearer to controllability

“…103 However, the as-synthesized alumina was amorphous and the surface area greatly decreased upon the subsequent crystallization procedure. [104][105][106][107] The salts are inexpensive and can be easily removed from the products by water washing. 16 Chen et al is the rst to introduce salts in SCS, which greatly increases the surface area of products in SCS.…”

“…104 The role of salts is believed to be two folds: decreasing the reaction temperature because the salt additives absorb reaction heat; salt precipitated in situ coats the newly formed nanoparticles, preventing them from sintering and agglomerating. [104][105][106][107] The salts are inexpensive and can be easily removed from the products by water washing. For the stoichiometric combustion reaction between nickel nitrate hexahydrate and citric acid, NaF is found to be more effective than NaCl for improving the surface area.…”

Evaluation of (BH)max and magnetic anisotropy of cobalt ferrite nanoparticles synthesized in gelatin

“…Several methods to synthesize CoFe 2 O 4 nanoparticles have been extensively studied, such as solgel process, thermal decomposition, co-precipitation, microemulsions, hydrothermal, and combustion reaction [8][9][10]. Among these, solution-phase chemical methods have attracted attention because allow to prepare nanocrystalline materials with high purity and controlled particle size at relatively low temperatures.…”

Facile fabrication of perovskite single-crystalline LaMnO3 nanocubes via a salt-assisted solution combustion process

“…This sensitivity to synthetic conditions implies that the LaMnO 3 nanocube reaction is under kinetic rather than thermodynamic control [25,26]. Several latest documents have also confirmed that the introduction of inert salt into solution combustion synthesis and tuning the addition of salt and fuel may provides a facile and novel route for inhibiting agglomeration as well as controlling size and morphology [27,28].…”
