Abstract

A TiO<sub>2</sub> powder compact was exposed to 2.45GHz microwave (0.1-0.8kW) for 0.5-60min and the response of TiO<sub>2</sub> was examined by measuring the surface temperature of the specimen. Anatase-type TiO<sub>2</sub> was heated up to 950°C but rutile-type TiO<sub>2</sub> was not heated. At a constant power output the temperature of anatase-type TiO<sub>2</sub> was higher for larger specimens, and at a constant specimen weight the temperature of the specimen was higher at higher power output. The grain size was larger in the bulk than near the compact surface. The transformation of anatase-type TiO<sub>2</sub> to rutile-type TiO<sub>2</sub> also proceeded more extensively in the bulk than near the surface. These differences were ascribed to the temperature difference caused by the small penetration depth of microwave in this oxide.
