ABSTRACT:
Disclosed are improved ceramic compositions which are useful in the formulation and fabrication of microwave susceptors for disposable packages for the microwave heating of food items and to such articles themselves. The compositions include certain metal salts as time/temperature profile moderators in addition to novel microwave absorbing materials and a binder. Certain metal salts can be used to dampen or lower the final temperatures reached upon microwave heating the ceramic compositions. Other metal salts can be used to increase or accelerate the final temperatures reached upon microwave heating. The microwave absorbing materials comprise ceramics with neutral lattice charges such as clays, talc, kaolin, silicates, aluminosilicates, sodium metasilicate, alumina and mixtures thereof. The compositions provide good heat generation and a predeterminable upper temperature limit. The materials are common and inexpensive.
