Effect of preparation method on the microstructure and optical properties of Y2O3-MgO composite ceramics

Yttrium oxide-magnesium oxide (Y2O3-MgO) composite nanopowders were synthesized via three distinct methods: sol-gel, co-precipitation and glycine-nitrate process. The synthesized powders were calcined at various temperatures, and their microstructure, specific surface area and particle size were characterized. A comparative study was conducted to assess the impact of the synthesis method on the microstructure and transparency of the resulting ceramic sintering. Notably, the powder synthesized by the sol-gel technique exhibited the highest specific surface area and superior light transmittance, reaching a maximum of 85.33% at a wavelength of 5.31 mu mu m.
