Dear Tayyab Hussain personally we never employed this interesting method, although we worked in the field or rare-earth metal chemistry for many years. However, I can suggest that you have a look at the following very instructive articles:

Solution Combustion Synthesis of Nanoscale Materials

Article Solution Combustion Synthesis of Nanoscale Materials

and

Solution Combustion Synthesis of Nanoscale Oxides and Their Composites

Article Solution Combustion Synthesis of Nanoscale Oxides and Their Composites

The good thing about both papers is that they has been posted by the authors as public full text on RG. Thus you can freely download them as pdf files. As a review article, the first paper willl certainly guide you to some potentially useful original research papers. In the second article it is mentioned that the combustion reaction occurs at ca. 400 °C. Instead of using a furnace, the combustion could also be initiated in a more simple way by using a normal kitchen microwave oven (IFB, 750 W, 2.45 GHz, 1.2 ft3).

I hope this helps answering your question. Good luck with your work and best wishes, Frank Edelmann
