Synthesis and characterization of Er2Sn2O7 nanocrystals by salt-assistant combustion method

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.…”

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].…”

Heat capacity of rare-earth stannates in the range 350–1000 K

“…In particular, such materials include rare-earth stannates, R 2 Sn 2 O 7 . There are published data on their synthesis [10][11][12][13][14][15][16], crystal growth [17], structure [18][19][20][21][22][23][24][25], magnetic [17,[26][27][28][29] and optical [1,24,30] properties, and luminescence [31,32]. At the same time, many properties of the rare-earth stannates, including their thermophysical properties, have not yet been investigated in sufficient detail.…”
