Solution-combustion synthesis of oxide nanoparticles from nitrate solutions containing glycine and urea: Thermodynamic aspects

详细

Solution-combustion synthesis (SCS) of nanoparticles was characterized by the temperature effect (ΔT_ad) calculated upon neglect by the temperature dependence of heat capacity. Thus calculated ΔT_ad values were found to be a linear function of the inverse radius of metal ions. Our calculations have shown that SCS reactions may yield not only oxides but also hydroxides and carbonates. Suggested was a simple formula for evaluating the ΔT_ad values attained in SCS of complex oxides.
