Microwave Heating of Ceramics 20151001 Ceramic

In microwave heating, a polar molecule is subject to electromagnetic radiation at a frequency that is in the microwave range. The materials' exposure to microwave energy causes rotation in the polar molecule, which results in heat being generated. This phenomenon is also referred to as dielectric heating. (A polar molecule is one that has an electric dipole moment, the best known being water.)
