Influence of combustion aids on suspension combustion synthesis of mullite powders

Single Step Solid Combustion Route for Preparing Nanosized NiO.

“…Sample (a) shows the formation of low crystalline phase of nickel metal as a major but there was minor evidence of the presence of nickel oxide. Sample b leads to an amorphous phase indicating in complete combustion reaction (18) . Raising the temperature to 400°C (Fig.…”

“…A good fuel should react non-violently and act as a complexant for metal cations (4) . Urea (CH 4 N 2 O) is the most popular fuel because it is commercially available, cheap (17) , produces high temperatures, generates low volume of gases (9,18) . The resulting product is usually a product that is dry, has high chemical homogeneity and purity, and is agglomerated into highly fluffy foam (19) by the escaping gases during the combustion reaction (20) .…”

Solution combustion synthesis of α-Al2O3 using urea

“…This method has also been successfully applied to the production of alumina [9][10][11][12][13][14][15] and other Al-based compounds [16][17][18][19][20][21][22][23][24][25].…”

“…The SCS process is based on redox reactions between metal salts and reducing agents such as glycine [12,14,16,21] or urea [9][10][11][12]17,18,24,25]. Generally, an organic reducing agent should also be a complexing agent.…”

Synthesis of Fluorite-Type Nanopowders by Citrate-Nitrate Auto-Combustion Process: A Systematic Approach

“…The parameters which affect the properties of the ultimate product are the type of organic fuel [4], the influence of the fuel content [5][6][7][8], the role of pH [9], the effect of various combustion aids [10] and inert salts [11], the effect of a dry combustion [12] or a wet combustion [13] and the influence of the ignition modality [14] or of the ignition temperature [15]. Those parameters have already been discussed in literatures.…”
