We have perfected a simple and inexpensive route for preparation of a variety of nanopowders by combustion synthesis called Glycine nitrate process (GNP). In this method the starting precursors is the nitrate salts of the desired materials which is dissolved in distilled water. Stoichiometric amount of glycine is dissolved in the same solution and shaken vigorously for complete solubilisation of the constituents. The solution contained in a beaker is then subjected to rapid heating on a hot plate to evaporate the liquid. Towards the end of evaporation a spontaneous flame develops and its burns vigorously for 1-5 seconds. The resultant ash is then subjected to calcinations at higher temperatures to eliminate any residual carbon in it.
