Abstract
The work presents results of solution combustion method utilization for yttria (Y2O3) nanopowder fabrication. Experiments
were carried out with four different reducing agents: urea, glycine, citric acid and malonic acid added in stoichiometric ratio. The
reactions were investigated using simultaneous DSC/DTA thermal analysis. After synthesis the reaction products were calcined at
temperature range of 800-1100°C and analyzed in terms of particle size, specific surface area and morphology. Best results were
obtained for nanoyttria powder produced from glycine. After calcination at temperature of 1100°C the powder exhibits in a form
of nanometric, globular particles of diameter <100 nm, according to SEM analysis. The dBET for thus obtained powder is 104 nm,
however the powder is agglomerated as the particle size measured by dynamic light scattering analysis is 1190 nm (dV50).
