Two component metal oxide nanoparticles such as lithium cobalt oxides (LiCoO2), indium tin oxides (ITO) were synthesized from aqueous aerosol precursors by the flame spray pyrolysis. A high enough flame temperature was used for the complete thermal decomposition of the aerosol precursor. Molar concentration of the aqueous precursor solution, and the flow rate of combustion gas such as hydrogen are varied to control particle size, size distribution and crystal structure. Crystalline LiCoO2 and ITO nanoparticles with the average particle diameter ranging from 11 to 35 nm and from 11 to 20 nm were synthesized, respectively.
