Abstract
A method for drying a ceramic article comprises providing microwave radiation from a microwave generating source, providing a ceramic honeycomb structure having a middle portion and at least one end, and exposing the ceramic honeycomb structure to the microwave radiation while shielding the at least one end from directly receiving the microwave radiation, such that the radiation absorbed by the middle portion is equal to or greater than the radiation absorbed by the at least one end, and the proper drying of the entire honeycomb structure without heat-induced structural degradation is thus ensured.
