Abstract
An electromagnetic susceptor for chemical processing having a matrix material that surrounds a non-matrix material that is made from a material that is different from the matrix material, the matrix material is constructed of a sintered ceramic material having lower dielectric losses compared to the non-matrix material, the non-matrix material initially absorbs electromagnetic energy applied to the electromagnetic susceptor to a greater extent than the matrix material, and the non-matrix material produces subsequent heat in the matrix material.
