Abstract
Highly transparent MgO ceramics have been prepared via Spark Plasma Sintering (SPS) at 1200°C for 10–60min, under a pressure of 100MPa. All of the prepared ceramics were visually transparent and exhibited relatively high in-line transmittance. The ceramic sintered for 60min demonstrated the highest in-line transmittance, of 60–80% in the 300nm to 9μm wavelength range; values that are close to that reported for MgO single crystals. Photoluminescence measurements revealed a peak located at ~360nm, which was determined to be due to oxygen vacancy color centers induced by the reducing atmosphere of the SPS process in vacuum atmosphere.
