Abstract
In this study, infrared (IR) and visible transparent MgO ceramics were obtained by spark plasma sintering of in-situ synthesized of LiF decorated MgO nanoparticles (MgO–LiF nanocomposite). Lithium acetate (LiAC), trifluoroacetic acid (TFA), oleic acid (OA), and absolute ethanol were used as in-situ synthesis of the LiF phase covered on MgO nanoparticles. TFA/Li (AC) mole ratio, pH, and calcination temperature were changed to obtain the MgO–LiF nanocomposite. The results revealed that with Li (AC)/TFA = 1.5:0.5 and pH = 6 at the calcination temperature of 700 °C, in situ MgO–LiF nanocomposites were well prepared. The SPSed MgO covered with a 0.5% LiF sample showed 30% more visible and IR transmittance than pure MgO bodies sintered at 1100 °C for 10 min.
