A New Method for Producing a Nanosized -Al2O3 Powder

A new method for producing a nanosized -Al2O3 powder was proposed, by which a saturated solution of aluminum oxychloride and sucrose was subjected to sequential heat treatment to 350 degrees C to form a transient species and then to 800 degrees C to form a nanosized -Al2O3 powder. The optimal treatment parameters were determined. Stages of the process were identified. The transient species and the nanosized -Al2O3 powder were studied.
