<p>High surface area α-alumina free of transitional aluminas and having a BET surface area greater in the range of about 30 to at least about 100 m2/g, and a method of producing same comprising the step of heating an α-alumina precursor, such as an aluminum hydroxide or a hydrated alumina, with a solvent, such as methanol, under conditions of temperature and pressure that are supercritical for the solvent. The resultant surface area may be controlled by the addition of water to the starting materials.</p> |
