IR-transparent MgO-Y2O3 ceramics by self-propagating high-temperature synthesis and spark plasma sintering
Source abstract
Abstract
Abstract A glycine–nitrate self-propagating high temperature synthesis (SHS) was developed to produce composite Y2O3–MgO nanopowders. Based on the thermodynamic calculations a 0.25YMg2(NO3)7-0.75NH2CH2COOH precursor composition was selected to prepare low agglomerated uniform composite yttria-magnesia powder. Near full dense composite ceramics were fabricated based on the prepared powders by the spark plasma sintering method. IR-transmittance and hardness of the Y2O3–MgO ceramics were studied in correlation with sintering conditions. The best transmittance of 80.9%@5 μm and Hv = 10.2 GPa were measured for the sample obtained at 1150 °C.
