Alumina powders used as a filler in rubber compounding was extracted from kaolin in H₂SO₄ solution employing conventional thermal and microwave energy resources. Maximum degrees of alumina extraction from kaolin were 72.8% at 80℃, 1M H₂SO₄, and 180min in the conventional thermal extraction process and were 99.0% at, 90℃, 1M H₂SO₄, and 60min in the microwave extraction one, respectively. The samples synthesized in both processes were analyzed by means of TG/DTA, XRD, SEM, Atomic Emission Spectroscopy, and FEET method. Studies are presently under way to unravel the basic interaction mechanisms between microwave and alumina power for high rates of alumina extraction from kaolin in the microwave extraction process.
