Abstract: 

Composite nanopowders Y2O3-MgO (1:1 by volume) were synthesized by the method of self-propagating glycine-nitrate synthesis with an excess of glycine and nitric acid. It was shown that freshly prepared powder (precursor) contains about 19 % of unreacted components and intermediate reaction products, which are removed by subsequent calcining. Crystallization of the precursor starts at calcination temperature above 600°C and leads to nucleation of the crystalline phases MgO and Y2O3. It was shown that calcining at temperatures from 800 to 1000 °C leads to the formation of nanocrystals with sizes from 20 to 90 nm, respectively. The specific surface area of composite nanopowders decreases from 48 to 16 m2/g with increasing calcination temperature in the range T = 700-1000°C. It was shown that during Y2O3-MgO calcination in the air, intense chemisorption of CO2 occurs on the surface of nanopowders. According to calculations, about 5 % of MgO is converted to magnesium carbonate. Finally,Y2O3-MgO composite ceramics with average grain size of 255 nm and transmittance of 71 % at λ = 6000 nm have been obtained by spark plasma sintering of synthesized nanopowders.
