Synthesis and study of nanocrystalline powders for an optical ceramic composed of magnesium aluminate spinel

摘要

Nanocrystalline powders of magnesium aluminate spinel (MgAl2O4) have been produced, and their morphological and structural properties have been studied. A comparative analysis of spinel samples synthesized by different liquid-phase methods has been carried out. Hot uniaxial pressing has been used to fabricate ceramic samples of spinel 15 mm in diameter and up to 2 mm thick. (C) 2015 Optical Society of America.
