Disclosed are ceramic compositions which are useful in the formulation and fabrication of microwave susceptors for disposable packages for the microwave heating of food items. The compositions include a novel microwave absorbing material and a binder. The novel microwave absorbing materials comprise ceramics with neutral lattice charges such as clays, kaolin, talc, silicates, alumina, aluminosilicates and mixtures thereof. The compositions provide good heat generation and a predeterminable upper temperature limit. The materials are common and inexpensive. Preferred compositions additionally include a temperature profile moderator which can be common salt.
