Estimating the term…
A microwave susceptor which includes a dielectric substrate and a dry layer of microwave active coating material overlaying at least a portion of the substrate is provided. The coating material includes a silicate binder and an active constituent and the weight ratio of the silicate to active is about 98:2 or less (i.e. less silicate). The dry layer is electrically continuous and has a surface concentration of active constituent of about 1 gram per square meter or greater. Sodium silicate is preferred as the binder and graphite is preferred as the active constituent. In addition additives such as saccharides, glycerine and plasticizers can be added to inhibit thermal shut down and to increase the flexibility of the dry layer. The susceptor can exhibit moderate heat performance or even high heating performance if desired. A susceptor baking cup, a baking system including a dome shaped cover which can be used to form an enclosure, and a container for frying are all possible uses for this microwave active coating material.
