Estimating the term…
A reflective temperature compensating microwave susceptor is disclosed. The susceptor has a microwave interactive heating layer which may be characterized in various ways. In one aspect, the microwave interactive heating layer is operable to provide an increase in reflectance by several factors during heating from 23.degree. C. to 250.degree. C. The microwave interactive heating layer may have a surface resistance that decreases significantly from 23.degree. C. to 250.degree. C. In another aspect, the microwave interactive heating layer may have an electrical conductivity which increases significantly from 23.degree. to 250.degree. C. The microwave interactive heating layer is preferably formed as a thin film deposited upon a substrate, preferably a sheet of polyester. The coated polyester is adhesively bonded to a support member. The microwave interactive heating layer preferably comprises TiO.sub.x, where x has a value between two and one. Most preferably, the microwave interactive heating layer predominantly comprises Ti.sub.2 O.sub.3.
