Oxidation and phase transformation behaviors of Si3N4-xMgAl2O4 (0 <x < 90 wt.%) nanocomposites in vacuum, air, and nitrogen atmospheres

This research investigates the oxidation behavior of nanocrystalline/amorphous Si3N4 compounds in atmospheres with different oxygen pressures. High purity nanocrystalline/amorphous Si3N4 and MgAl2O4 mixtures were used to investigate oxidation behavior of Si3N4. Si3N4-xMgAl2O4 (0
