Abstract: A microwave heating package, and a method of microwave heating. Both the package and the method employ a lossy chemical susceptor which upon continued exposure to microwave radiation becomes substantially microwave transparent, thus building into the system a unique maximum temperature shut off at the point at which the chemical susceptor becomes microwave transparent. The chemical susceptor is comprised of a combination of a solute, such as inorganic salts of Group IA and IIA, and a polar solvent for the solute, such as water. The chemical susceptor may be composed of a hydrated form of the inorganic salts. The package, method and chemical susceptor may be used for microwave heating of many products, including among others, food products.

A dielectric constant of at least 2000 and a limited change in dielectric constant with temperature is present in compositions having the approximate formula:Pb.sub.x .multidot.Ba.sub.y .multidot.Sr.sub.z (Nb.sub.2 O.sub.6)where x, y and z represent the mole fractions of each of Pb, Ba and Sr which are in the ranges of X=0.1 to 0.4, y=0.1 to 0.4, z=0.4 to 0.5, the sum of x, y and z being 1.
