Ultrafine yttrium aluminum garnet (Y3Al5O12, YAG) powders were synthesized by sol-gel combustion process from a mixed solution containing aluminum and yttrium nitrates. The precursor and powders were characterized using X-ray diffraction, thermogravimetry-differential scanning calorimetry-mass spectrometry, and transmission electronic microscope. Mono-phase cubic powders were obtained at 900oC by directly crystallizing from amorphous materials and no intermediate phase was observed. The powders processed at 900oC were uniform and in good dispersity with average particle size of about 20 nm.

Lead zirconate titanate powders are derived from a novel aqueous-based citrate-nitrate/oxynitrate sol-gel combustion process. Aqueous solutions of metal nitrates or oxynitrates are transformed into gels with citric acid under heating. The received gels undergo a self-propagating combustion reaction on heating to 180 °C and subsequently yield voluminous ashes. These ashes form single phase perovskite Pb(Zr0.53Ti0.47)O3 powder with a specific surface area of 8 m2/g upon calcination at 550 °C. The ashes show a homogeneous distribution of lead, zirconium, and titanium ions which guarantees short diffusion paths in solid state formation of PZT perovskite. The redox behavior of the gels was studied with the help of DTA experiments. Powders are characterized in terms of XRD, SEM, and EDX analysis.
