Stabilization of #gamma#-aluminum oxynitride (ALON) and preparation of ALON bonded corundum refractory

摘要

In order to prepare ALON bonded corundum refractories, the formation and stabilization of aluminum oxynitride spinel (ALON) during reaction between Al_2O_3 and AlN and sintering of corundum-AlN-active Al_2O_3 were studied. It was found that MgO was a proper stabilizer. The AlN/Al_2O_3 ratio is improtant for sintering. The proper ratio is about 11/89.
