Microwave susceptor with attenuator for heat control

摘要

A thermocompensating susceptor is described comprising a microwave transparent sheet, e.g. paper, paperboard or plastic, having a layer thereon of a dried dispersion comprising a film forming vehicle together with two kinds of dispersed particles including microwave intractive particles such as a metal, metal oxide, carbon or graphite that absorbs microwave energy to produce heat in a microwave oven and electrically nonconductive thermocompensating particles of a mineral hydrate containing bound water of crystallization and having a dissociation temperature between about 100 DEG F. and 500 DEG F., at which temperature the bound water is released therefrom to prevent overheating of the laminate.
